Im installing a sneaky pete kit on my car soon, and since my last Zex kit I didnt have to worry about fuel delivery, I didnt upgrade anything . I have a Walbro 255 pump that I just installed but now I need to know the best route to go so I can get more fuel into the cylinders. I searched but didnt really get a clear answer. I have seen some tk6 ECU chips with different fuel maps , but with a $500 Dollar purchase price, to hell with that.
Any suggestions would help
