hey guys i need some help on my msp. upgrades are gt28rs, custom fmic with relocated maf on cold side with hks bov,custom intake, corksport exhaust,tubular manifold,mbc set at 10 psi and the ssafc. now when i give it gas i can feel it dumping more fuel cause it seems like the turbo hesitates and the aem wideband is pegged out at 10.0 at half throttle. it was always running rich like 12 afr or so when stomped but not at half throttle its 10.0 afr. any ideas would be great help. gotta love the msp lol. thanks
