I have a feeling the ISF with I/H/E/Reflash + DR's would be a beast at the drag strip. With a 7200 or 7400 rev limit option, a great DA track and Caymandiver at the helm, I could see 11.5's a possibility.

It's nice in the 80s here in CA. The increase torque curve really makes launching a bit more challenging, now it just wants to roast the tires with traction control off in 1st and part of 2nd. I'm also running on wider 275 Michelin PSS.

Now that will be interesting to see!

I'm running 275/245 Michelin PSS and before the tune I was already having traction issues. Now with the tune is even worse. I'd like to go with 295/255 PSS but I'm not sure if they'll fit in the rear with a fender roll since my wheels have a 42 offset. I'm also not sure if anyone would buy the set of PSS with about 3500 miles on them.

Another option for those not seeing rain in the summer would be R-comp tires.

Interesting... what brand/model are you currently running? Are you having traction issues on hard straight line acceleration when the tires are cold, or mainly when taking hard corners and applying the throttle?
If you're having traction issues on your massive rears I wonder how others will hold up. Right now I'm running a square setup 265 all around with Michelin PSS. With my wheel size I'm probably limited to running 275 max without modding fenders.

word... Calgary is at 3500'
My car literally feels like a different animal when I get it down to the coast.
I've seen the following formula on numerous sites throughout the years.
elevation x 0.00003 x horsepower at sea level
3500' x 0.00003 x 467 = 49hp loss

I have no doubts that this tune is great and worth the money, but the some of the reviews are probably getting a bit exaggerated which is common when new power mods come out. The reality is when we add a new power mod, we tend to drive harder and use more throttle than normal because we're excited. Considering the fact that ECU has been reset, the prior fuzzy logic memory is wiped clean thus the car is relearning your new driving style. That's why people often reset ECUs on a somewhat regular basis (i.e., to wipe out the learned laziness). Compound that with colder temps being experienced in most areas of the country, it can make the car feel perhaps faster than you think.

^Exactly. My one week old M235 6MT will easily light the tires up from a 50mph or lower roll. The car is quite torquey, but the spinning is largely thanks to 20-30 degree temps and MPSS "summer" tires.
