I think you guys who are blaming the driver are FOS.
With an extra 30-40 hp on tap, the mph should increase by at least 3.
And it doesn't matter how bad the 60ft was.
Hitting the rev limiter .....hard....could cause a loss in mph, but this is only a prob in low gear.
I ran 14.7 @ 98 stock, wheel hopping like a bitch. Before the trans grenaded.
And I only have a few thousand runs down the 1/4 mile in the last 30 years.
Something else is amiss here.
I'd suggest removing the aftermarket CAI, and getting it reflashed.
Go try it again.
Most if not all others have posted positive results from the stage 2.

well.. and he said he didnt really notice much of a diff when driving. that alone is something to consider

 

well im going to try these spark plugs and see what happens, i got the NGK BKR7E, i am going to gap them at 0.040. Andrew i cant really blame my 60 ft because when i ran stock i got a 14.7 with the same 60ft time.

 

well, you'll be stoked on the 4th I'll bet!!
make sure to take it up close to 7000 each gear too - didya get a shift light??? helps alot....

 

all the ignorant unknowledgable posts in here are scary... shifting eariler doesnt allow the torque curve to drop because torque doesnt produce all the way up to the redline... and also why would someone say that he didnt get the flash? Hes redlining at 7k! Finally if you run a slower 60ft time then ur prob gonna have a higher trap speed because you would have more time to build speed, not all the time so dont get on my ass but still thats a possibility and Wow im not even gona bother wit the other stuff lol all i can say is good luck at the track next time man
