Good morning,
I have a stock bottom end LS1
BTR stage 2 turbo cam (220/23X .618"/.618" 113 LSA)
fast 102 with a 102mm throttle body
stock ls1 coil packs
stock ls1 injectors.
1 7/8 headers, 3" collectors
2.5" exhaust with Borla x-pipe muffler.
t56 magnum trans
ACT LW flywheel and single disk clutch.
I am new to tuning and have only really messed with VE tables for speed density tuning on my old 5.3l.
The 5.7l was tuned in a previous car by a tuner who is no longer around so I cant ask him for help.
The car runs fine other than having issues with a surging idle. It will run fine for 30 seconds or so then start surging. I checked the map sensor Cal. and it is reading correctly according to my local weather station. I see that the timing is fluctuating but I am still trying to figure out if that is the cause of the issue or a symptom.
The only DTC i have is for a failed MAF, but from what I can tell it is disabled in the tune.
I'm sorry for the shortness of this post I am trying to get this out there before I leave for work. I will check back as often as I can throughout the night to answer any questions or clarify anything.
Thank you for any help, John
