Bought a 95 850 with a 19t, manual swap, ard blue tune. Issue I'm having is the rpm hanging or even increasing slightly after abruptly letting off to shift. car slightly surges after letting off the throttle in gear as well but not as noticeable under load. The ard tune is for a manual swap and have no lights on.
Other question I have is what air fuel ratio and egt temp should I be seeing. In a 3rd or 4th wot pull I'm seeing a low of 9.5 a/f for a second then around 10.5-11.5 at wot 18psi. Could this be something wrong on the car or is it all ecu tuning related? My egt cruising are 700 and get up to a max of 1200 on a hard pull, is this safe?
I'm considering keeping the blue tune as a backup to run on 93 and getting a custom tune from tightmopedman for e85 and larger injectors, sound worthwhile?
Also while cruising maintaining speed out of boost a/f is between 15-16, is this safe and just meant to conserve fuel under light loads?
