No, but it is the fastest way for the ECM to get rid of the stock TB data. It will get replaced anyway (w/o reset) but it may take longer. It is no big deal if you do not reset.

Most obvious It feel likes the power has been filled in from right off idle up to to 3K... which makes the sweep into higher rpms much smoother.... Linear.... Just like the ad said. LOL

Actually coming off the gas at 5500 rpm in second gear and being able to feather the throttle into a corner was not possible before but is now.... Previously i would have to set my corner speed before entering the turn, roll the corner and gas the exit. Now i can drive through the corner.. if that makes any sense to you.

fine throttle control i guess is the correct term? It was exactly what i was looking for.

Can you blip the throttle off idle like a cable connected Carb?

Will be very interesting comparison for me having had the TMTB.

Your review is the one I’m waiting for since you have used the TM TB and will be able to do a bette comparison between the two.

Plus I’ve seen your attention to detail when describing things (that’s a compliment ) hahaha.

wow that was shipped fast. you sent it priority from Alabama yesterday and its out for delivery today in western ny. over night. that works out perfect im taking a 700 mile trip to Cecil County Drag way tomorrow.

Looking forward to a review after you get it installed! Good luck in the races!

wont be racing but ill let you know. if this is something you would like to try maybe we could put it on your car so you can try it.

Are these typically shipping same day?

I ordered on Thursday and didn't get any notification yet. I'm not in a huge rush it just seems like everyone else is reporting basically same day shipping.

rlarsen, and all other members. Thank you very much for your orders. Yes, we usually ship the same day, until the Camaro6 enthusiasm depleted our stock. Obviously, we were not prepared for such a wonderful welcome we've had here.

Anyway, we are working nights and weekends to ship pending orders as fast as we can. As of this moment, all pending orders will ship Monday, you should see notification e-mails in your inboxes over the weekend.

This is only temporary, we are taking the necessary measures to get back to the usual same-day shipping.

Thank you very much,

[blueg1]

Im in for the lt5 TB when it becomes available.

There is a much debated problem w/ the throttle response of the LT1/LT4 engines, manual or auto, the issue has been described in this and other forums (Corvette, Camaro, CTS-V, Trucks, SUV’s), just to mention a few descriptions:

- Throttle Lag
- Delayed response
- Car feeling heavy or not nimble
- Difficulty climbing hills at low/moderate throttle
- Uncertainty when passing other cars or unpredictable response at low/moderate throttle
- Stumble when shifting on manual transmissions

You name it, this has been my issue w/ my Corvette 7 since test driving at the dealership. I've tried a Throttle controller, AFM disabler, ECM Tuning, and arguably the three most talked about ported throttle bodies (PTB) out there. I have also combined some of the above w/ some success but still not enough. One just needs to hop into almost any other comparable car to feel they respond better.

After spending so much time/money, I decided to take it upon myself to find out, I also have all the equipment needed at work (measuring, testing, simulating, machining etc.)

Long story short; it is the throttle body. Between idle (~5 degree throttle) to ~30 deg throttle angle the amount of mass air flow (which is proportional to power) puts our cars at a weigh to power ratio similar to that of trucks and SUV’s, both in terms of absolute value and rate of change. Not to be confused w/ the weight to power ratio that is usually published, which is calculated at WOT, above 35 deg throttle angle our engines shine. It is on the part throttle range (idle to 30 deg) that the issue exists.

I’m not going to speculate on the reasons, but I can tell you that our throttle body p/n 12678223 or 12620263 is used in many GM vehicles and that such throttle response helps w/ fuel economy. That helps to keep parts cost low and meet EPA requirements for the fleet. However, I do not think one size fits all and that a high performance car needs to sacrifice performance for economy.

The throttle controller and the tune improve response by making the throttle plate move faster between the 5-30 deg range. Faster, but it still needs to go through a tortuous path for the air flow, and the manifold pressure doesn’t recover as fast. It is a transient process, and it is from the intake manifold where the pistons suck the air from. Notice that this is not true throttle response, it is just tricking the ECM into thinking you have pushed the accelerator pedal harder. The actual throttle response is the same, only physical changes to the throttle can make for a true throttle response.

The existing aftermarket ported throttle bodies also helped, they do change the throttle physically, but their effect only starts to take place at about 25 deg in what I thought was the best one of them. Definitely a step in the right direction, but I noticed they were not optimized and that more could be extracted from them, that is a throttle body that can increase the absolute value and rate of change of mass air flow right from idle and up to 35 degrees to achieve the same weight to power ratio (in that range) of similar high performance cars that feel nimble and fun to drive at part throttle.

Another long story short, I reversed engineered 10ea OEM throttle bodies, 3ea aftermarket ported throttle bodies, and a benchmark (competing car maker model) OEM throttle body. Optimized/modified the OEM throttle body to meet the benchmark throttle response as well as the goal stated above.

Our modified throttle bodies (MTB) are made (CNC machined) from a brand new OEM throttle body, flow and engine tested. Our design has been fully vetted by Corvette 7, Camaro 6, CTS-V owners, fully and openly tested by Corvette Forum members mainly. Driven in different conditions/modes for a few thousands of miles now at extreme temperatures and altitudes.

See pics below for more insight into what I’m talking about…and most importantly what do you think? All comments welcome.

Thanks,

Thanks for providing all this detail. I have a few comments and questions:

• I'm surprised the air flow at the closed position (5%) is not impacted compared to stock. From the pictures, it looks like there's a higher effective flow area with the throttle blade closed. Can you comment on this?
• Is idle stability / speed impacted at all?
• Is the control module targeting a MAF command and adjusting accordingly? Over time, will it "learn" back to similar response levels to stock in order to hit the same air flow commands?
• I'd like to see a Torx style screw used vs. Phillips. In the first close-up, it looks like the Phillips head is buggered up a little bit from being tightened down. The stock throttle body uses the Torx style with higher torque capacity before deforming the head.
• If this impacts air flow and thus power levels, I'd argue that it could be considered something that could void the powertrain warranty if GM / dealer techs wanted to. It might have a relatively small impact on power levels and mechanical limits, but it would be hard to prove that it has no impact.

How do i ship the core back, i'm not seeing anything in the package with instructions on this.

Thanks Alain, it's "out for delivery" !

You know... if this does fix it... I'm going to want my M6 back

Thanks for the fast response!

Guess I waited one day too long haha. Glad to hear you are catching up quick though.

I will actually be installing this at the same time I revert to the stock intake and green filter from a Roto-fab.
