I have a 01 lb7 truck thats been a pain since day 1 lol.
To start the truck has never been tuned. I put a set of LDS injectors in the truck 10k miles ago, has new fuel lines from tank to ficm, new fprv, fass 150 and a hellman sump, 5" exhaust, afe air intake and new filters. I have always had a p0093 code when towing any load and just recently the truck started getting very sluggish in 1st and 2nd gear. Its as if its not getting the fuel it needs to spool the turbo, once into 3rd it will spool around 2k rpm and feels somewhat normal. After the loss in power I occasionally get a p0101 maf code and a p0089 fprv code. I have cleaned the maf with maf cleaner multiple times and it seems fine and have replaced the fprv with a bosch oem unit. I have heard of the 01 OS are horrible and that the ecms can become currupt. I recently put my buddies edge cts on the truck and logged actual vs desired fp and followed within 1k. Any suggestions before spend the money on a kennedy pretuned ecm?
