LS1edit? Tuning? Advice please... After a LT header w/ off-road pipes and O2 sims intall, I seem to be running way too rich. A Diablo Predator Scanner saw fuel trim levels at 10% positive and O2 at 965 mV at WOT. This would seem to account for me being 3 tenths and 4 mph slower than I was stock. (13.3@109 stock -- now 13.6 @ 105). Obviously I have lost some power and needs to do some tuning and adjusting...
What is the best way to go about this? Do I buy LS1edit and then have a pro do the tuning for me? If so -- where is the closest, well-known and respected LS1 tuner to Detroit?
Thanks.

Re: LS1edit? Tuning? Advice please... You could practically buy LS1 Edit for the price of one tune (not counting that you need scanning software and a laptop).
The LTs seem to have made you rich, and it wouldn't take much research to figure-out how to adjust that within LS1 Edit. Basically just multiplying the Injector Flow Rate table by a percentage less than 100%, and also, for WOT, multiplying the PE vs RPM table by a percenatge less than 100%. Plus, in the future, you'll definitely need to make adjustments, whether code editing, or more a/f or timing adjustment. Good luck!

Re: LS1edit? Tuning? Advice please... I really know very little about the computer tuning which you guys just talked about... messing with that stuff would really make me nervous. Is it really that easy? It seems like I could really screw something up if I didn't do it right. Thanks for the info so far

Re: LS1edit? Tuning? Advice please... Its pretty simple, but you need Autotap to see how the changes affect the car. If you need help ask, their are plenty of knowledgable people on this board who can help. Also you can go to http://www.LS1tuning.com/forums/ it is specifcally for LS1 edit.
