I'm trying to help a friend tune his CTSV. It's a 2009 with upper/lower pulley, intake, and some FIC 850cc injectors. I got the Excel data sheet from them, plugged in the values, and the car is pegging the LTFTs at -25%. To me, it seems the injectors are over-delivering based on what I put in there. I need to go a few emails deeper with them as at the moment they're pointing the finger at the pump which, based on my last log, seems to be getting the job done. We need to get the fuel trims in order before changing anything fuel related. Hoping some on here have been down this road.
