So you guys might laugh at me for this... first off let me list what i'm working with when it comes to the vehicle etc...
2007 Saturn Sky Redline
2.5" exhaust no muffler (it's still pretty quiet)
fabbed intake pip with k&n filter
fabbed charge pipe (turbo side) with recirc hks ssqv3
Maf relocated to about 1" from what i believe is an IAT for the charge side
Factory bov hooked to boost to keep it shut (damn thing leaks)
the hks is hooked to the manifold to allow fast enough response time (solenoid from ecu is looped and doesn't throw code)
Alright now with all that said... VCM Suite of course (otherwise i'd be posting in some other forum...) The tune i'm running is a much more aggressive tune than what i've seen some others run for cam timing (works like a charm and always has) and i finally relocated the maf... that's where the issues have come in... i WAS running around 22psi with this tune and was having issues of it going lean during the summer and super rich in the winter (this being while i finally relocated the maf)
I'm attempting the standard method for LTFT+STFT for calibrating the maf... while this is making a difference... it only seems to be making a difference until i hit boost... once i hit boost the ecu freaks and enters limp mode... now with this being said... it's hitting the right afr... stft are bouncing between -10 and +6%... it started out pegging at -20% for both... i'm going to make another cruise around and get it a bit closer... but i can't get any load readings above 120% because it kills boost. it's getting -1 degree of knock retard (which happens when it starts to miss under boost)... i'm thinking about yanking my spark plugs and giving them an inspection just to eliminate that from a possible issue. commanded afr is .87... misfire happens when afr drops under .92... i can hold 1-2psi without it freaking out but you can feel the misfires...
Any info as to what maybe a cause is welcomed... spark timing is running stock atm (i put it back to stock to eliminate that as a risk or problem)
