to **** with torque limits.

The people’s champion has spoken, no more limits!!!

I’d guess that it’s also in the tune, no big deal it just needs to be revised possibly. It takes some time and a few revisions to get the car running just right. My car has had a few revisions and It will most likely get a few more.

I had the same issue that was tuned out by Matt last week actually. I’d lose power in second gear until I took my foot off the pedal. This happened first at the track then on a couple of hard street launches. After sending him an email and explaining the problem I received a revision maybe an hour later and the problem seems to be solved.

I run my best times with TC, ON!
I’m not PP though so it’s never really off anyway.

I always lose a lot of time with tc on. The other day i made a couple draggy runs and it was over a half second slower with it on. I wonder what makes some cars better with tc on but not others.

Don’t have a draggy so this was never tested on the street. But, on a prepped strip I always suffer less spin with it on.

Flexer here as well! kinda 1/4 mile numbers are you running?
I was wondering does turning the shift pressure down hurt times? I also have a jolting 1-2 shift happening with me and was thinking of turning the shift pressure down but does that mean the shifts would be slower that would eventually hurt times?

I have yet to have a good pass in this thing. I’ll let you know when it happens.

I expect you Flex’s to beat a TRX.

LOL I did see that and that flex is MOVING! That one runs 12.5, if I can have mine in the 12s, ill be happy lol. Im fairly close, just a 93 tune at the moment and ran a best of 13.3 @ 103.5 so DPs and intercooler should definitely get me in the 12s

It takes time to dial them in! I see so many Flex’s but none are modified around these hur parts.

I have an e30 tune just waiting on fuel it stuff to get here, chasing a woman this weekend maybe back to the track next weekend.
The shifting issue has been a bummer. Lol it has been perfect on the street. But if I go to the track where I get full traction it won’t shift.
I went 13.90s once and that was shirt shifting second which then jumped into 3rd. 2500 da. Last week couldn’t get a run in. It absolutely refused to go into second. (400 da) I’ll do the trans mount and e30 tune next.

since I’m still waiting on the revised shift point tune from GH
