DR's Installed. TC comes on all the damn time now.

kttxz06 · 05-24-2018, 10:31 PM

Just put on my MT Streets. 305/35/20's. TC blinks all the damn time now, car seems to rev out. I turn all nannies off, runs fine.

Something my tuner can help with on calibration or just way of life?

Did he even finish tuning it yet? Is the cam installed?

Nope, we are never done tuning. Last pull was 803/768. Running into heat issues honestly, so not too pleased, but I just ordered my ice tank and block plates so we can get some more flow going. And yes, cam is done and we CNC'd the heads, ported the blower and snout while the motor was apart.

Should be going back again..........sometime end of next week to dial it in. Was hoping for 850ish. Not sure if I'll hit that # in this Houston heat right now.

The 35 aspect ratio is causing a problem. The difference in diameter between the front & rear tires is causing your issue. I think your tuner can resolve it easily.

laynlo15 · 05-24-2018, 11:25 PM

Can't change it, just can't be over an 1" diameter difference. But, you are probably over the 1" difference as stated above.. Just run a taller tire in the front and should be good to go.

yeah, you're over an inch taller than stock. Matt can fix that.

Thank you. Yea, I shot him out an email. i figured it was something like that. If anything, I can roll with nannies off now. These DR's grip like a mutha now so. I did a few WOT hits with nannies off and it stayed straight so. Drive home in the rain was interesting yesterday when installed. haha.

Next up. 100 shot!!!!!!! Maybe 150.

How did you get that tire to fit without rub issues? I have them on my 18 ZL1 and they rub the inner fenders, even with 8mm spacers they barely clear.

I have aftermarket wheels so the offset is different. I do still get a little rub since I'm on BMR springs. But nothing major.

meSSohappy · 07-12-2018, 11:27 PM

So I was able to run my DRs on the street with a 4mm spacer. Got 8 turns on my lug nuts. There was still some rubbing going over bumps but all wil be ok at the strip. I did a burnout on the street and picked up some loose gravel on the way home. It appears the rubbing is from the rocks that got stuck in my tires.

What I think of when people put taller than stock height tires on a camaro....

FWIW, I would not recommend running TC ever with a boosted car and modified tune (when you are full throttle). When TC is enacted the tune is altered and may cause engine damage.

I leave all nannies off now anyways.
