triple boost pod with oil temp/press/voltage

then andy forrest for ecutek remap

never went for a parallel supply on my wrx and went to 400 bhp ish on the standard short engine with no issue,

anybody with know how???

Shouldn't be needed at that power level on a newage car. The top feed injectors are better than the side feed style on the classic cars. That said, it will aid fuel delivery...

its a 2003 engine conversion in a classic so should be fine then as is

As long as you have top feed injectors, should be fine. IMO.

yeah its top feed pinks from a 2004 so no worries then lol thought that was another 2 or 3 hundred i was gonna have to pay out there lol
