Been gearing up for the track. So testing the car wm tune if I'm at a 60 roll and stomp it it pulls hard till 120 and feels like it hits the limiter.
If I back of and come back in to it it will keep pulling but hesitating.. so what I am confused about is if I do a 0 to 135 data log no issues.
Any ideas? Torrie asked if it was spark blow out?
I have new plugs I'm going to drop in but he said it's physical... don't know why it won't do it all the time just high speeds 120+ from a roll.
Of course in Mexico

Do you have any logs of the 60+ pulls?

I have personally noticed that if I am rolling around 60 and I stomp on it fuel curves are very different than from a stop...

Going from 2k rpms to to 4-5k rpms is a lot for a fuel system to just pick up...

Although at 120 you are shifting into 5th gear?!

Gotta ask though... 1/4 tracks you won't see north of 120 (fifth gear) unless you have been hanging out with BPD?

Top of 5th but I'm also spraying on a # 6 625 ml nozzle 100% meth on ethanol blend. E27 what it took to get to 93 oct. but yes that makes a lot of sense seems like it didn't like it as much as a dig. As for 120 nah not up here at 5200 elevation definitely not on stock turbos

Throttle closing most likely... he probably has you looking at 4 pids for throttle... check out absolute..

I guess I can log starting with the paddles at around 4 k vs kick down see what that does . No reason to be up there anyways. Now I know.
But wanted to know I could go threw all the gears if needed on a highway roll race .
