Default Questions

guys, I tried the car on the strip this last Friday. I could only muster up a 10.70, and could feel the PTM interfering with the car. I had my 18" drag wheel/tire setup on, and no TPMS sensors. The car wouldn't let me get into the sub-modes in the track app, or let me put the traction system completely off.

What are you guys doing to get this thing to quit interfering with your pulls down the 1/4 mile? Can you tune out the computer to allow you access all the time?

also, the MT ET street SS are super dangerous on the highways! I thought it'd be ok, but they were all over the road on the way home.

also, what tires do you recommend for the street? The MPSS are no good for roll racing.
I lose it at 95mph with them.

What size turbos are you running if you're finding MPSS to be unsafe and losing traction at 95mph?

UM..............did you forget to air up your M/T Streets before you left the strip? ANY tire with very low air pressure would be "all over the road", and dangerous. Just askin..........

The MT are all over no matter what psi is in them. Have you ran them?
They were 28 on the road and 18 at the track

I cannot help with the PTM interference issue, but i am subscribing to this thread, because I just ordered 18" wheels with Hoosier DR's and M&H Skinny's and I am also planning on running them without the TPMS sensors.
As a result, I am also concerned about the car pulling power with this setup, even though my car is a bone stock C7Z A8.

Only muster a 10.70? Doesn't sound too shabby to me.

thanks, but the car should go 10.2 or so.
I'm going to have my tuner look at it and see if he can get me in the track apps without sensors in the rear wheels.
