Im kind of unsure of what I should do. Right now im running my h22 on a p13, and I have a p28 sitting here for when I boost. What im unsure on is this. If I go ahead and pay to get my p28 chiped for crome, will I have to have the ecu re-chiped when I boost? If thats the matter, im assuming its probably best to wait until I boost to use the p28. I just dont want to waste money chipping it now, if I have to pay again later to have it re chiped.

 

i think it probably better to wait. then u can get it chipped and tuned while its boosted. at least thats what im doing

 

I agree, just wait that way you have everything on the car that will need tuned, and you'd want to chip the ECU to best suit the mods on the car.
