hehe, i know its abit of of a waste on an auto rolla, but i think with my set up now my auto is doing pretty well even though it could do better. My project its to get 100kw atw once i get that im happy to stop. And plus for me any gain is a good gain, i know the tb should cost around 300, installation i can do myself. I need the extra bit of air so i can get a better tune for the car. Also my car is alot faster compared to a stock auto rolla, as some of you guys remember me and black toy had our lil benchmark, i think i did pretty well. Currently my car it doing 8.5 seconds 0 to 100 on the gtech which im happy about. 1/4 not sure but once i get that done i will be going to wsid for sure, and i will be hunting for the 15s. Cheers any help would be good
