This NGM ECU reflash was designed to be used with the MP62 Stage II Sniper supercharger kit or the Stage II Alpine supercharger equivilant. Two supercharger pulley combinations can be used with this reflash. You can use a 2.8" supercharger pulley and 6.0" (OE) crank pulley or a 3.3" supercharger pulley and a 7.0" crank pulley. Both pulley combinations will yield 6-7lb boost range. The mods for this reflash are  catback exhaust, headers, CAI or SRI, 360cc injectors, NGM Tri-Flo 70mm throttle body and the above pulley combinations. The reflash has optimized ignition timing, 7300 RPM Rev limit, cooling fan optimization, accurate air fuel tuning, lower full load detection, complete drivability tuned to within 2% long term fuel trims. This reflash was tuned using 40psi fuel rail pressure at idle with 53+psi at wide open throttle. Driveability is spot on and power throughout the curve is, well the dyno sheet tells all.

There are two options. You can send us your ECU for reflash or we can reflash a core that we have in stock. Option two will have a $200.00 core charge added to the reflash price. When we receive your ECU back as a core, we will refund back the $200.00 charge.
