Not really sure what is going on here. I keep changing the MAF transfer function but my wideband is only getting marginally better - still lean. I am now virtually maxed out on the MAF transfer function and this does not seem right. I also noticed that the MAF gms/sec is very unstable.
Possibly a bad MAF? Bad MAF placement? I don't like how they placed the MAF in this turbo kit. Did I mess up something in the tuning? I have scaled the tune for FMS 39# injectors which I believe has been done correctly.
I am attaching the stock tune named Flash and my modified tune Flash3. I am also attaching the scan from a WOT pull to 5000 with 5 psi boost. 2005 GT.
Any help is appreciated.
