#7275, "RE: upgrading inefficiant componets according to mass air flow senser." In response to In response to 4
If you are going to use the stock MAF you are not going to be able to achieve more than 500hp. That is what it is rated at because that is all the air it can flow.
To achieve that you will need.
Fuel pump - Walbro 255HP Injectors - Probably 880's to get that high Wideband O2 sensor SAFC & Datalogger or DSMlink for injector tuning Bigger turbo - Probably 50 trim or bigger New Intake Pipe Front Mount Intercooler Hard Piping for the intercooler Upgraded BOV Fuel Pressure Regulator Boost Controller Wastegate (if turbo is not internally gated) 3" Exhaust - Turbo Back
Those components along with a lot of tuning time or dyno time will get you near the 500hp mark if your stock engine doesn't break.
