Question about fuel pump and tuning.

Wasnt really sure where to put this smiley-nixweiss but if I install a walbro 255 on my already tuned spec, will it make my car run rich, therefore needing some retuning? Sorry if it seems like a noob question.

Re: Question about fuel pump and tuning.

Do you have to modify your fuel system any to run the 190lph pump? What about if you wanna use an aftermarket regulator??

Unfortunately, you can't go to a 255 with the stock returnless FPR-in-tank.

I'm using the 255.  all I did was modify the plastic pump housing (drilled 3 holes) and larger injectors, of course.

You only need to modify the fuel pump canister for the 190lph. The FPR can stay stock.
