I have a 2007 GT with a TR-6060, full exhaust, and Saleen blower, and 4.10 gears. I believe something is wrong with the traction control. Even with the traction control button off, the car acts like traction control is active in first gear. After first gear, the car runs like a scalded dog. It has been professionally tuned and built. Any ideas what this problem may be?

Pull codes. Initial instinct is TPS.

The engine light is not on. Shouldn't it be if a code is thrown? Shouldn't the car act up in the other gears also?

Not necessarily, depends on what's actually wrong.

If the TPS is acting up then the symptoms would lessen once the throttle body was open and RPMs were up.

Just spit balling though. Pull codes.

I tried pulling codes with the old programmer I had for it. The programmer said no codes are being thrown.

Hmmm...

I'd ask for your AFR but many folks don't run a wideband.

Check timing.

With the car off and key on, put a meter on the TPS and measure voltage. Manually operate the throttle and ensure that voltage is scaling as throttle blade moves.

Run KOER if you haven't already.

It's definitely not a tune related issue. Timing and AFR are fine. I'm not sure about the TPS voltage though.

I will say this. I've been through three transmissions. After the stock one was replaced with a TKO-600, the car started doing this. Are there any wires or parts that could've been damaged during a transmission swap?

I took the car out this morning and it acted fine. I thought it could be a problem when warmed up, but it acted fine after it reached operating temp also. This bug has me stumped.

is the car bucking or just has a hard time taking off/ very poor accel? could be cam timing being too retarded. make sure your air intake tube is fully seated on the throttle body as well.. ive seen this cause similar symptoms

The clutch has about 500 miles on it. It's a McLeod Stage 3. It's not bucking. It's not a timing issue. The intake tube is sealed. The feels almost identical to traction control kicking in.

Like I was saying, it has no problems past 1st gear. It doesn't act up in 1st all the time either.
