Of course I installed LT's and 4:10s blah blah blah... just like everyone else the 4:10s made the biggest difference in ET but the headers ehh not so much. So my question is how much of a difference will a tuner tuned by the right guy make in my ET. Keeping in mind I'm lucky to run a 13.9 lately and has never been tuned.
yeah you should really lower those 555rs down like whitestang was saying. my car is on the stock 245 tires right now and there bald i lowered them to 25psi and i was dropping it at about 2100 and pulling off 13.8s and 13.9s just find the sweet spot for your set up.
