[QUOTE=Badmojo;10038571]Are there any details beyond the SEMA YouTube video on the GM Performance Pack?


This is exactly what I'm waiting for and GM has nothing to offer as to its release date...frustrating!

Is it likely that the only upgrades available are to Camaro's <ZL1 & 1LE ? The ZL1 parts trickle down to other Camaro's. Those of us with the ZL1's will have to settle for what we have...period?

Has it thrown any codes?

I'm also very curious to see what your numbers are like after a tune.

02 sensors kwav8r, We'll handle that on Wensday, the hp number I'll post it Wensday as well. I did all the work here at my shop/full time place I'm employed at.

Dude that is a seriously risky decision. Was the 670 RWHP pre tune? If so what was your AFR?

I'm assuming that's WOT during the dyno run. That's pretty dam impressive with no tune.

It may also be impressive when he has to order a new LT4...

Hopefully we’re not going to see a whole “no tune” train because of this one example.

My thoughts exactly. Sometimes people get away with things...sometimes only once. I would not recommend it to anyone.

OP, I doubt you could get Hellcat RWHP/TWTQ numbers from just bolt-ons that do not require a tune. Hellcats consistently make well into the 600s with some even hitting the high 600s. I've seen that ZL1s are typically in the mid to high 500s. So if you had one that dynoed high from the factory and matched up with a Hellcat that dynoed low and then added no-tune-required bolt-ons to your ZL1 then you'd be pretty much neck and neck. But that is about the only way it'll happen. But don't get number crazy. The HC has a lot of power but it also weighs in at like 4200-4400 pounds with nobody in it, lol!! Stock to stock on a roll race and you'd be even trans to trans. Stock to stock on a dig and you should be able to beat one provided you have the A10. But for the most part, if you wanna bang heads with them based on the numbers, you'll need mods that require a tune and a tune. And even then you'd have a disadvantage as they make approx 750 to the wheels on 93 octane with just a pulley and tune.

I'll see what kind of hp it makes Wensday an I hope it doesn't blow up on the dyno. I'll have about $3800.00 invested an making close to 700hp if not 700hp to the tires. I'm good with that...i could've sent my car to a shop to get all this done but I enjoy fighting with headers and all the rest of the bolt on parts that gave me a fit. I know i saved a few bucks by doing it myself except tuning it on the dyno. Anybody want a 2018 Harley Davidson Street Glide CVO....just kidding...I WANT A DYNO!!!
