[QUOTE="Skud, post: 14326255, member: 16758"] Well - upon the advice of James (Tuning By James) I swapped out the ID1000s with my old SD 60s and pretty much all the issues I've been having are gone. I swapped the injectors and loaded the 60lb injector values into my tune (scaled 0.47). When I fired the car it was a bit rich. I took out 15% from the MTF and the trims are within 5% of 1.0. Nothing else was changed. The problems I've had that are now fixed: - Lean spot between 2500 - 3000RPM - AFR changing with load/RPM. Rich low load, high RPM, etc. There were very distinct transition points where the AFR would jump up or down 10%. - AFR changing with fuel pressure. I'd see a 10% difference in fuelling between 39 and 45psi - AFR changing with how heat soaked the car is. I'd see a 1 - 1.5 point movement whether or not the car was soaked. I'm going to get in touch with ID to see what's up. With all the success people have with the ID1000s it's possible I just got a bad set. Riley [/QUOTE]
