be very careful about that.

what makes you think it needs to be tuned? who are you taking it to? are you sure that tuner knows what he's doing? there are few that actually do...

i'd recommend just doing a run at 10psi on a dyno with a wideband setup to get an idea of whether the car even needs to be tuned. it might be good already.

degeesman posted the link for the FAQ - check it out.

the FAQ has some very good info on fuel setups and figuring out when you need it. you might benefit from larger 1200cc or 1300cc secondary injectors and maybe an upgraded fuel pump, but that really depends on your current duty cycle and whether or not your ECU supports the larger pump and injectors.

 

Sorry I'm a newbie. But how would I find if my ecu would support larger pump and injectors. If not should I get a new ecu. Thanks.

 

Good call.
