Problems with TFS engine combo..wont idle right and sputters when you give it throttl

Sounds like you are running too lean. Give the FPR a few turns and try that out. I have close to the same combo, and when I first drove it, my autometer gauge was off and I was running around 24 fuel pressure. Needless to say it popped, backfired, and ran like garbage. It runs great now that I figured out the problem and upped the fuel pressure to 44. I also have the TFS cam and have not had problems with it.
