that is the "calculator" factor in track surface temps, track prep and changing of tires, that is what issue was but I can just tell you are one of those people that know everything. I've made 50 passes in this car in 4 months I think I know what's going on.

I by no means know everything. You make lots of passes, just making sure you are processing the information you’re gathering. Don’t get upset towards me. You also got skinnies in the front vs the stock wheels before and still lost as much as you did. DA doesn’t affect boosted cars as much as NA. Like you saw, a 11.0 at 129 converts to high 10.8s at 131. That’s far from 10.50s at 138. Unless those were timing malfunctions. Not saying anything is wrong with tune.....but could be wrong with the car. Bad quality gas.....boost leak...etc.

Im pretty sure tune is adjusted according to intake temps coolant temps etc, so my first outing with this car the car went 11.4 @129 and 11.3 @127.7 very hot day. both those passes were made on M/T Street SS tires, then I switch to m/t R and the car started to hook and also go faster nothing was changed in between. A few days later I went back to the track and went 10.9 10.8 and 10.7 mph vary between 131 and 133 this was a decent day it was hotter but not humid at all, the following week I went back again to the track and 10.51 @135 10.57 @ 138 this day was in the low 70s no humidity at all, the last pass I broke and axle using the transbrake. I think the weather really effects my tune and car the humidity is a killer. I went to track rental in July the it was 80 degrees all day but DA was only 1000 the 11 passes I made were between 10.50 and 10.7 131-135mph. I check for boost leaks didn't have any but I will be swapping out my plugs this week. When I swap back to M/t street R and go to the track I will report back.

Still swapping back to R's? Whens the next track day for you? I'm still a few grand away..fuel system, smaller pulley, tune..etc.. shit is expensive.

Butt dyno results are the only ones that matter. How are you measuring boost? Whens the next track day?

Dyno results mean nothing it's just a number, 1/4 miles times give you an idea of real power to the ground. I rig up analog boost gauge, and tee it from the boost reference point behind throttle body and just run long vacuum line to inside the car, not permanent. I only use it for few pulls then throw it on the glove box and unhook vacuum. I will get to the track once weld fixes this leaking wheel I wasted a whole weekend because of them they better do the right thing I will find out today.
