Fuel cut?

[sapper12b]

My car has been acting up ever since I installed the UICP and FP intake pipe. I really only notice it when I get on the highway in 3rd gear. It is at around 4500 rpms and it cuts out. I don't think it is like hitting a wall, but it just completely looses power and then a second or two later, I am good to keep going as long as I do not go above that rpm range. Is my ECU reading too much air? I am still running the stock fuel pump. Yes I followed the instructions on Full Throttle on setting the dip switches on the MAFT and they are set correctly. Any help or suggestions would be great. Thanks.

Do a boost leak test.

sounds like you could be running out of pump but usually your check engine light will flash on, at least if it causes knock. If your profile is up to date i'm guessing your running out of pump.

Yeah, my air compressor took a crap on me last week, so I need to get a new one and will be doing a BLT. The bike pump just doesn't cut it.
