INSTALLED ACCUFAB,75mm,CAI,& Predator???

[Ryan's 02 GT]

I just took the car out after installing these parts and did not notice a whole lot of SOTP gains. Both the intake and 75mm are ACCUFAB and the CAI is the Demolet full lenght one. I was hoping for more pick-up Maybe I should have held out for a S/C. Also anyone with the ACCUFAB stuff notice a slight whistle when you barely give it gas? Thanks

I noticed quite a bit when I installed mine. Expecially over 3k.

And the whistling is normal.

Definately woke mine up above 3K as well - that's when you can really notice the difference.
Mine doesn't whistle at all though...check all you connections again...something maybe loose or leaking and causing a loss in power.

I don't see gears in your sig. Your gains may not be as noticable as most who've done a gear swap, since you don't rip through the gears and reach the upper RPM as quickly.

I have 3.73 waiting for install. I may be just too easy on the thing. I usally shift at 3000-3500. I did drive around more today and did notice some difference in the upper RPM's.

With my P&Pd plenum I didnt notice a difference rightaway, but after a while I could tell that the car pulls pretty strong all the way to 5800 with not much drop off like it did before. I know torque is dropping, but the rpms pull right to 5800 without the feel or sound of the car loosing a ton of power.

Disconnect the battery and leave it off for 10 minutes to reset the PCM. You'll probably notice a difference then...

If I disconnect the battery will I loose the Predator tune?

 

[Kilgore Trout]

No, I asked that same question a couple months ago and many people said no... Will not lose the tune.

Correct. The tune is held in the same flash NVM (non-volatile memory) as the factory tune was. Disconnecting the battery will reset the PCMs learned parameters which are stored in different battery-backed RAM. Upon re-boot, the PCM will test that memory, see it's been "corrupted" and reset it to factory defaults. It provides essentially a "clean sheet of paper" for the PCM to re-learn. Ryan, you might find the idle is a bit wonky at first since closed loop idle control parameters are some of those that are held in battery-backed RAM. It'll figure it all out again...no worries.

trinity_gt, You seem to have gotten good numbers from the bolts ons you did.
I should have gone and had mine dynoed first but oh well. I'll go and disconnect now. Thanks guy
