1) The car is completely traction limited in 1st gear by gently laying on the throttle.
2) car traction limited in parts of 2nd gear including when I short shift it into 2nd, this was NOT the case stock or before E85.

Throttle response is much improved which is needed because of the above. The car is crispier.

Power under the curve from 3000 to 6400 is noticeable. Meaning this adds power over the entire band. vs the MSD which really is high mid to top end only.

Every once in a while I smell vodka.

Best overall mod in terms of street performance that I made, best bang for the dollar and this is with the initial tune.
MPG is down about 20% cost of fuel is down about 20%

I intend to do heads and cam this summer, but really the car is almost the max that I can enjoy and still keep the shinny side up.

LOL on the vodka. Adding power back on the low and mid range by itself sounds good to me. Here is south Jersey there is only 1 gas station that has it convenient. So I will not be running it all the time. 93 the rest. Are there any other ill effects of burning E85 besides reduced gas mileage?

I agree about the power, it is a waste on the street. Already had one go shiny side down, but not by me. For me I would enjoy going deeper into the 11s or being able to pull an 11 on a so-so DA day. I hope my clutch lasts.

Where do you teach and what department? You have my dream job.

Oldman,

Once you get some time to spend on data logging I will send you a new file with improved timing in the upper load areas. I'd prefer to stay a bit conservative until I have the ECM data to reference. There is another M6 on the forum running the more aggressive timing with no issues. I'm running it on my car as well.

Mouthwash will cover up that vodka smell LOL

What sort of delta are you seeing from stock to a 93 tune and then to an E85/flex tune Tim?

This was my car.

Thank You! We appreciate it!

Primary reason I decided to go to long tubes vs Hooker Tri-Y sorties, is the 12 ft lbs of midrange power.

I did baby steps to full E85 and as I did not know if the magic was all going to work. I had no issues, so I would not anticipate any issues swapping back and forth between 93 and E85 (which on my pump says can go as low as E70).

Teaching is a sweet gig, I teach in the workforce field but can teach in Math, CS, Management Info etc. I work for a large U, but will soon retire to a small Catholic U.

With traction control off (full stupid) the car is quite the handful and that is before heads and cam... LOL. I had a 440 Dart from high school to just a few years back, so I'm use to handfuls... but this M6 is really a handful.

I worry about my clutch too. I have about 6K miles on the car and the back tires are near bald and my other set are showing wear too....

The double clutch is $1000 bucks or so, oh well. I did a lot of work on Bob's two Lingenfelter LS1 383s so my memory of clutch problems and George McCleod... are deep and painful. It really was GM's elchepo PLASTIC internal slave which was not fixed to the metal ZO6.... a pox on the designer... aka bean counter.

Thanks Tim.

Even though Ethanol is over $2 a litre for me, I'm still tempted just to do some mustang bothering at the track!

$1.58/gal here

Don't rub it in!
I can only get it in bottles, even premium pump is about $5.70 a gallon here.

Ouch!

After reading all the replies it seems like I should just stick with the stock box and possibly upgrade to a ported TB instead?

The real question was in regards of how an intake will affect performance because I will be upgrading my headers/catback. If it makes no difference then that is fine by me.

I am waiting to see your results. They are 15% off now, so makes them a good deal. I'm either getting the AFE intake OR a belt driven powered intake...
