yep, wheatley's got that pcm somewhere in his pile. I never saw my stock tune.

 

get the PNs off the injectors..

 

Ok guys here's the log from today, it goes into PE, but it's still knocking, still lean. I'm almost convinced it's an air leak....I could swear I hear something whistling when getting on the highway with the radio off...

The first 100% TPS is with the truck in 2nd, straight 2nd gear punch
The next one is a 4-2 drop on the highway.

 

looks alot better, but yea check for a leak and go from there.
Just get a wideband on there and see what its doin...

 

what ya doing with those intake gaskets you have hanging up on your wall nonnie?

 

they are goin on my 4.8.. sorry. haha
ill see if my buddy has any in his shop when i get home.

 

get a wideband form trick, there really cheap.

get on holden crazy and look at your stock tune.

 

I changed my IFR to 24.8, it was 25.2.....not sure if that makes any difference

 

that will lean it out a bit..... not sure how much tho.. shouldnt be to much I owuldnt think.

 

hmmm....I've got a 2000 5.3 tune pulled up and the injector pulse width voltages are different than my 02 lq4 tune...

Even looking at a 2002 4.8 tune it has the injectors listed as 25.2 lbs/hr??? What's up with that
