Put the tune in,and the airraid air filter and got lean codes banks 1 and 2.Have since re checked all my work and tightened things up.If I reinstall the tune and still get the code,what should I do next?It was 25% lean before I went back to stock and tightened everything up.Can I adjust that stuff w/my DIABLO?Thanks.

Is this just an air filter replacement, or a whole CAI?

I cant imagine a CAI leaning you out that much...
What do the fuel trims look like with the stock tune?

yeah, sounds like something wasn't clamped up tight and you were getting additional extra air sucked in from somewhere for sure...

I know of 2 Vararam users with the tune not having your issue (me and Lost Angel). Sounds like extra air is coming from somewhere....

I never had this issue before either!I clamped up everything again and will reinstall the tune later and see what happens.25% is alot of leanness!!

I know that and I didn't even stay at a holiday inn last night!!

Just the big filter airraid makes.No idea.I cut a hole in the shroud too for some real outside air.How do I find the fuel trims?

I had the same problem in fuel bank one.K&N intake,tightened up band clamps ,which looked tight already and no more engine light.
I have my fuel trims close to perfect now and car runs great. Good luck.
Try some data logging and run the log through dataredux and that might help you out.

Never heard of that.How do I find it?Thanks for the info,btw.Also,I was able to adjust fans and all that w/my 05 predator but I don't see or forgot where the screen is on this u7194 unit.How do I get in there??

it's in there... you can't adjust the fan temps, but you can adjust the % power that the fans run at...

when you go into Modify Tune, I think it's the first or second parameter in the list... Fan Control, or Fans, or something like that...
