Bump. I’m in the same boat and just one of the pumps go out on me. I want to know if I can replace the pumps to something bigger or if I have to replace with what the kit came with. If the later, would anyone know what pump to replace it with?
No modifications needed to the pipe, just have to trim plastic on the car to make room for the valve. I read that they just released a different pipe that puts the MAF in a different location to help with drivability. I was tuned by Lund on E85 and everything was smooth.
