Could you tell me what is the boost psi on the base tune and torque & HP numbers? I don't want a rebuild right away I like to take it step by step for the experience and financial reasons too

Im sitting at 400hp on quite a low reading dyno. And its having no issues.

And at 400hp it is just quite absurd to be quite honest! anything above half throttle in auto mode to get on it a bit from a roll and your spinning wheels.

In manual mode getting on it decently it just spins 1/2/3 if your really into it. Fun but a bit scary!.

Driving in auto mode is actually realllllly sketchy if you are rolling along and decide do lay into it. You will just go sideways. SC might be a bit diff to turbo in that respect though as its not a rush of boost all at one time.

How much torque are you putting down?

Will try and go 265+ on rear next time I think.

I was thinking of that tire size next time around. Do you currently rub? I heard 265s will rub a little in the rear unless you shave back the tab on the bumper.

No rubbing yet. Have a few ppl over here running 265+ in the rear depends on offset I guess and how low you actually are?

I'm close to you, at 323 and 255/40/17's 1st and 2nd are worthless. But boy is it fun once you hook up. I can't imagian what 400 would be like.

How are you guys all handling the rev limiter with the increased power?

I'm asking because at least on my JRSC + HBP+ E85 car, I will hit the limiter before the trans is able to shift from 1st to 2nd in automatic mode.

Normally I'm in manual mode when I want to have fun and I shift it when needed to account for that.

Just wondering.

I also notice that there is a slight delay in the shift from 1st to 2nd and 2nd to 3rd when I'm full out. As in I click the paddle but I stay in gear still accelerating for a split second longer. The shift itself seems pretty quick once it starts.

I have the same hanging issue.

When I'm shifting above 4k and on the throttle, the RPM dips like it's suppose to, but you're able to see a little waver at exactly 4k before it starts climbing in the RPMs again.

For me with 255lb of torque and it's slipping like crazy. Wheels no spinning but revs would climb and sometimes my fourth gear would disappear totally in manual mode. The revs would drop to idle and I would have to shift down to 3rd gear instead.

Soloside · 03-10-2017, 01:24 PM

Has anyone here experienced the P2757 CEL?

The light ONLY happens when I'm in 4th gear at more than half throttle.
