Serious Issue

Just start from scratch and get this thing setup correctly for starters. Adjust your tps exactly like brad wrote. Set your base timing and idle properly, refer to vfaq if you don't know how. Verify your idle switch is working. Verify your isc is working. Get a bypass plate to block off the fiav to rule it out, plus you will never have to worry about it again. No idea what injectors you have but ensure your injectors settings are decent. Make sure your o2 sensor is working, or just force it into open loop.

Hooked up a scan tool today. Adjusted the tps to 0%.. air/fuel is a little better not 100% idle is sitting at 12.8-13.2 and cruising its at 14.8-15.2... ideal would be idle n cruise to be 14.2-14.6. Still gotta do a boost leak test and I did not install the bypass plate yet. My tuner told me idle should be at 5% so after I do a blt I'll adjust the tps to 5% n see what happens. Scan tool only shows % not volts. O2 sensor and maf sensor seemed be to okay also.
