Hey guys,
(thought this was appropriate in the performance section, since noo codes, and happening under boost)
I have not been driving the MSP much, and when I do, its normally not for a beat run, but yesterday I took the car out, and when I spooled it up, it went lean, and it was repeatable...not just a fluke etc.
While at 10psi the AFR's were starting in 12's and getting leaner !!!!
Good thing I keep an eye on the wideband
I lowered the boost to 6/7psi stock, And the car stayed in the 11's for a while then increased to mid/upper 12's in the upper rpm, which still scared me.
I changed my SSFTC for more fuel , and the car still runs lean. No codes, this is only noticed when in boost, outside of the diagnostic region of the car. And the car has great vacuum 21 inHg.
I eventually put the map back to all 10's (in which case my car normally BOGGGGS down to 10.2 -9.8 AFR piggg rich.)
But the car sweeps from 11.1 through 12.4 in the upper rpm.....
Other issues with the car: The car takes a while to fire (crank speed is fine). It also will stumble and die right after starting sometimes. I first thought it was because I removed the VTCS flaps, maybe it is another symptom though.
Can someone please help me? This car has me at wits end.
