A/F adjustment needed??

[CanadaMarauder]

I know I know another Air fuel ratio thread but just curious if it's worth playing with after tune and JLT CAI. I have DR tune (AMAZING) and JLT CAI again best purchases I've ever made for the car...have Flowmasters and res delete tips.I have no access to Dyno and i am no where near Known Marauder specialists...ANYWAY is it worth adjusting A/F to try and get a little more...or is it just a waste of time for 1hp and possible engine damage...so many threads so many different answers.....help
Thanx

P.S. no drivability problems just getting power hungry :burnout:

Dennis is usually VERY helpful with tunes.

You can, however, help yourself. Download Extreme Tune from SCT. This will allow you to richen or lean your mixture, adjust timing, adjust shift points etc.

Making these adjustments on your own is not for the faint of heart and will require trial and error to meet your preferences. You'll have to start by asking DR to email you a base tune.

Further, while one gains tons of adjustability, loading a tune into the Xcal from Extreme Tune will remove the on-screen adjustable parameters from the Xcal, so you'll have to refer to your PC for future tuning.

My experience: I ran DR's base tune lean by 4% with absolutely no issues. A few folks down here in SFL, have run his tune ALL THE WAY LEAN at the track without issue, notably on a 100K mile motor.

Of course YMMV, but that's the best I can tell ya!

If you don't have access to a dyno at least buy a stand-alone wideband to verify any adjustments on your own.
