well, sounds like you covered all the bases... so it could be that your CAI is really working that well.... which CAI, Volant??

clean your mass air meter yet?

Did you de-screen the MAF? this can sometime throw your ltft's out of whack as well, depending on the configuration of the intake pipes.

Stock MAF, just cleaned it. Have not modified the MAF
CAI is the K&N FPIK Fuel Injection Performance Kit. This mounts the MAF just downstream of the filter then a 20" tube which curves up to the throttle body.
Since I haven't found any problems and it runs fine I am temped to reinstall the 87 tune then after re-logging data make an LIFT adjustment up to 20%
Sound reasonable?
Could I hurt anything?

hmmmm......K&N.......You didn't oil the pee out of the element and get your MAF glazed with oil....did ya?

I have a DRY element CAI......

Oil pretty dry on the K&N and just cleaned MAF even though looked clean & shinny
I will try the change and let you know
Thanks for all your inputs.

Update...installed 87 tune and after logging adjusted LIFT -18....settled into -.78
Looks good and drives great!! Thanks to Grumpy and 06MonteSS for your help.
Question... if I want to try the 91/93 Tune should I use the same LIFT adj or do I have to re-log first?
Thanks

you can use the same slope adjustment... just put on the miles and re-log it afterwards just to double-check...

damn, that is a lot of adjustment for no vacuum leaks and a functioning MAF

must admit, first one I've seen that far out of whack out of the box....sounds like you're getting it there, though. Excellent.

Yeah I was thinking that the changes I made, CAI and more free flowing exhaust cat-back, exceeded the computers range of adjustment(I know probably a stretch). Now by re-centering the adjustment the computer can control within its range of adjustment.

I mean, I have a CAI, and a FM muffler (NOT cat-back)... I wouldn't have thought it would do that much, but, at this moment, I am speechless...LOL

Ya I know, I may still have a leak somewhere but it is sure running nice so I will see how it goes.
If it were an airplane I would see if it would make book performance numbers to confirm HP/Performance.
I guess I could do 0 to 60 times against known data, but I just put the studded snows on so that will have to wait.

Lift +25??
