trey...... all your pulls were made on the utec map???

 

Yes they were; no changes to the ecu or map.

 

trey, out of curiosity have you ever tried a CAI, i switched from OEM to stillen and found exactly what you did, than swapped to INJEN CAI and i gained +5whp over stock airbox. Lost i believe 4 hp with stillen .

 

So with a gain or loss of 4 to 5 hp, what exactly are we looking at in terms of 0 to 60mph times? I'm guessing a 1/2 second more or less. And again, keyword here is "guessing".

 

10 lb/ft of rear wheel torque is roughly 0.1 seconds in zero to 60. 5 Hp would be half that or 0.05 seconds. Give or take 5% assumming G35.
10 HP is insignificant in a 3500 pound vehicle. Even worse 10 HP won't improve top speed by even 2 MPH.
