trying to find out with my mods (turboback exaust,injen intake,mbc 23lbs,andwalbro fuel pump) if i can remove these mods put the car back to stock form would i need to retune or would the car run fine with current tune and could i just leave the fuel pump.thanks any help greatly appreciated.

 

you will need to flash back to the stock rom because youre tuned to have a free flowing exhaust and yes you would be able to use the same fuel pump but will be running rich
