i read something about the 22r engine if you move the tps back you can change the power band. i know what it is doing is just tricking the ecu to give the engine more fuel before it needs it thus setting your power band lower. well i did this to my 1mz-fe and my engine check light came on. well it did this before it did this and i didn't ever find what was setting it of. i dont have a obd2 checker. well it did it agian but not after a while after i did it so i want to know if this mod i just messing with it more. and the car does pickup a hell of a lot faster.
