Does anyone know what figures my MAF Should be putting out under load? The maximum it will produce is 210.1 g/s and there is a slight hesitation/stutter when in the higher gears at half throttle. Stage 1 remap,Walbro fuel pump, Excedy performance clutch kit, HKS mushroom filter, Mongoose full system including 3" turbo downpipe and an HKS blow off valve. Also my AF reading when on boost/full throttle was 11.4 and boost is peaking at 20psi and holding slightly less. No CEL, idle seems okay too but with MAFs I know they're a bit tricky to fault find...

The remap was carried out before I bought the car, I am now wondering if perhaps its Stage 2 map or it's stage 2 setup running on the Stage 1 map? But need to make sure that MAF figure is good or not.

Thanks
