HPP is a waste of coinage.....

WoW like you I would have figured that dropped you into the 12's.. It might be running to rich with the headers. Might look at your AFR. DO you know what your AFR was before you started?

[dfillmore827]

no i have no clue on that, wuts killing me is tghe 2 mph drop and same time

[Z28Thunder]

I agree just seems like something (computer) is holding the motor back. Any knock codes since the header install? Do they hit on anything at WOT?

[dfillmore827]

no, i have 02 sims

[Z28Thunder]

If the headers were hitting at WOT sensor could think of it as knock and retard the motor. I would look at AFR.. With you lossing MPH seems like it fell on its face at the begining of the run. What was your 60'..

1.9 and 2.0 on street tires, also, a power fuel tune is on with the hpp3

[Z28Thunder]

Not a fan of hpp3... Power Fuel tune???? Can the Power Fuel tune be taken off?

[dfillmore827]

yea it has non rfg and rfg, or stock, rfg= reformulated gasoline. u can turn the power tune off

[Z28Thunder]

Did you try it in all modes? Non rfg,rfg and stock???

[dfillmore827]

tried rfg and non rfg and it changes a little, not much but its either positive or negative depends on day of the week

[Z28Thunder]

Might as well try stock...

[dfillmore827]

yea maybe, can get any worse, before i had headers i ran 13.1 @ 106 so it has to be something with air to fuel
