BlownSRT... i have been around this for many years and i have to agree that the 1/4 times you are hoping for are unrealistic... general rule of thumb for each tenth in the quarter you either have to gain ten horsepower or lose about a hundred lbs of weight... the quarter time you got of 14.5 is a great feat... but to run 13.5 you have to either gain 100 hp or lose 1,000 lbs or a combination of the two... the chip at best is a 10 - 20 hp investment, air intake a 10 hp investment at best if any, the exhaust will be lucky to see 5 hp in this under pushed 3.2... your friends Z is running 13.9 with 60 - 80 more hp (mattering on year) which sounds right on target for the difference between your times and his...

its not that we don't want to believe you... hell, i wish i could cause i am not satisfied with the power... but it really is not going to happen with those modifications...

WET nitrous kit [75 hp jet]... custom intake... custom free flowing exhaust... no chip (it advances timing, a no no with nitrous, don't risk it)... and i see you running those kinds of times... nitrous kit will cost you $500 - $600 bux. i have had great luck with NX brand...
