03 Cobra vs. New C5 Vette - You wouldn't believe the result

[srv1]

Another simple trick to take .2 off the ET for the turbo Buick car is to use a paper clip to jump the ALDL connector and have the torque convertor lock-up automatically after 2nd gear.

If i recall, that puts GM's in base timing mode. Why would you want to do that?

I will admit that those TTAs definitely hook at the track. The first car I ever raced on my very first pass was an 89 TTA when I had a V2 S-trim @ 12 psi running street radials.

Maybe i am wrong, but all TTA's were Turbo'd AND RARE! Why would someone take a potent motor with a turbo and change it to S/C? You sure it wasnt just a T/A with a S/C and a V8? That dude would make more power by keeping the turbo rather than switching. How often do you see these TTA's? No flame, just a question.
