When you lower the car, it changes the drive line angle so it might be best to install a taller tire on the rear to fill the gap between the tire and fender plus a taller tire (larger circumference) will change the final drive a bit making the 3.73's more streetable.
While your at it, you might want to consider a somewhat larger outer diameter rear skin. It would help offset the 3.73's plus fill in the wheel wells without throwing the drive line angle off.
Yes, I contacted Brenspeed and added the tune they recommended. It made a dramatic improvement plus my car is an automatic and it was like I added a new transmission to the car!
If you add a custom tune it will spruce them up.
I installed the Pypes exterminator and went big deal, then I added the tune and it sounds considerably better.
Take it out and beat the crap out of it and see if that helps......
I have had that problem in the past with other cars but not the Stang. Your rear drains are plugged. Normally they blow compressed air in it to clean them out.
Should be able to do it yourself.
Warlock, I am with you...... I questioned it as my other cars start in 1st no matter what position its in (unless you select manual mode).
Seems very strange that a performance trans would even want to start in 2nd or 3rd but who am I.
They charge for Diagnostic time if no warranty problem is found. I think thats a good way to make money.
I have reset the computer and it acts the way it should now.
It will be in 4th at 24 mph if you feather the gas but runs out to redline when you hammer it and no starting in 2nd from dead...
I have a 2006 GT with 10k on the clock. Just bought it so I am unsure how the trans. should respond.
50% of the time the car will start in 2nd gear even from a dead stop.
It really seems to load the torque converter harder than it likes.
Is mine the only one like this or is this common...
