Just got back from the track and I could not believe 3 times in a row. last month the best I could get was a 15.66 in the 1/4 mile. I put on a GT muffler, green air filter, and put an ice pack in the breather and I got 15.21, 15.23,and a 15.30. can't wait to get a tune! dash for the cash ready.
The you'll really love what a tune will do for you car!!! Yeah, ditching the stock muffler for a good exhaust is good for around 10RWHP....
Wonder if that ice theory actually works, ive heard of people doin git, but a 15.2 at the track with an auto defiantely shows that it does.
