Got my ecu & chip back from msd this morning in record time, found no faults although they did adjust the chip slightly as i forgot to mention the 4x4 inlet & spacer i had

Cruise whise the fueling is bang on at 14.4 - 14.8

Idle is still very rich and also on boost, now i was playing around on idle and when you slightly press the throttle almost nothing the fuel drops right off to 14-14.5

could this be due to a tps fault ? i did set the tps a while back to what i though was ok, it also sometimes drops off its self then richens up again
