You're correct about the weather affecting your times. It's been abnormally hot(70's & 80's) up here in the NE recently, and that will slow down your car. Suggest that you go to the track when the weather conditions are similar to what they were when you ran your best time w/o 4.10's, and then compare. It has already cooled down into the 50's today.

I know the weather is playing a role, I'm just wondering if I should be running faster. I assume you guys w/ improve times also increased your mph?

my times were actually slower as well.. I ran a 13.2@103mph w/intake&tune, but with 4.10s its a 13.3 consistent@102mph.

It feels alot more aggressive off the line, but it's not translating to better times though...

Ya, I'm going do another track day soon on a "cooler" day. the gears for sure make the car rip off the line. I also have bama tunes, there sending me new tunes because my car did through 2 codes like 2 weeks ago (tq calculation & some kind of circulation venting or something).
