havent made a pass yet,actually havent even started it yet. just got a razor alky kit too along with some other parts. i got the ext.extreme chip used from a guy without knowing that i needed a ls1 maf sensor to work with it and i just got the maf and new pipe for it yesterday so it should be running soon. i doubt it will put down any good numbers with the stock suspension. only thing i got is airbags,still need more funds for control arms.
