If you have stock injectors, and you're running the boost as instructed by Autothority, there's no reason that the MAF kit shouldn't work straight out of the box; no tuning from other sources necessary.
There's something else up with your car (low voltage somewhere, fuel pressure regulator not working properly, weak fuel pump; just to start) or maybe a false reading from the wideband.

I dont think a Blown headgasket would have been a false reading. That prob resulted from Old gasket + Running lean there is a problem with how the fuel is mapped with the chips i bet

I'm running 15 PSI, my vaccum is fine 17 to 22 hg. Injectors are brand new from FiveO motorsport(Ebay). Fuel pressure regulator is brand new and it shows 39PSI at idle. Wideband is brand new AEM.

I'm almost 100% sure. I already spoke with Russel Berry and he's going to take at the fuel maps. I also ordered is MAXHP kit with different maps.

That's right Sebastian sorry If I didn't say it correctely. Russel is going to read my current DME chip and it's going to add more fuel. I also got his board and he was nice and offered other maps to see if one works correctly. Really nice guy, I wonder why he got banned from rennlist?

Sebastian how's your AFR's.

Sorry for the OT, but since when did Russell get banned from Rennlist?? He's always been a great guy to deal with from my perspective...

But you have PH chips, maybe you are OK since you are running a total different setup. If you get a chance install one just for piece of mind.

I believe it had to do with not paying sponoship fees.

OK, Ill bite. Why is it unwise to adjust your a/f ratio with an afpr ?

Thanks

I think that if you have areas where your chips are running rich you may wash your cylinders. But people with more experience please chime in.

Well, I know for a fact I'm running way too rich. Just finished installing my wideband and I read 10:1 when I mash on the gas before boost hits in. I idle at 13.5:1 once warmed up, and in the 11-12.5:1 when cold lol.
Normal cruising is around 14.2-14.7:1 and under full throttle its is in the 12's until almost redline it goes into low almost high 13's
That's with fqs set to +3% fuel and adj fpr at 3 bar and old LR chips that allow fqs changes.
I need to probably set the fuel to -3% and do fpr that way so that it doesn't run so rich down low.
