like the topic says, i dont want to take my eg through inspection on the sniffer test with 750's i want to take it through with stock injectors and stock p28.
will it work? if not i think i can tweak the 750's but i think it will be easier to swap out. ill post this in the FI forum as well for the stand alone guys.

u cant run a 3-bar on a Stock ECU. it will most likly trip CEL and run horrible.
if ur car is tuned really good with the 750cc then u should be able to pass inspection
u can also wire in the stock map sensor in parallel to the 3-bar wires, but cut the signal wire going to the 3-bar and put it on the stock map sensor. then u will need to run the stock ecu and u can put the stock injectors back on
another thing, r ur 750cc injectors high or low impedance. if they r low u will need to bypass the resistor box
