map sensor codes

[AFAsucks]

hey Tobi ever since i put in the 450cc injectors my ecu throws a map sensor code but not when its under boost....it throws it when im in gear and decelerating. if i put in the clutch and slow down its fine but if i leave it in gear and let off the gas to slow down it throws the map sensor code. it started happening right after i put in the injectors. the missing link is still in so i dont know why its even throwing the code....especially becaiuse it throws it under vaccum not boost. any idea whats going on?

damn....so there's no way to get around that huh? i was wondering if it has anything to do with the "deceleration air" setting it has on it. i was told not to mess around with it when i had the stock injectors in but do i need to mess with it now? curious only because it happens when im decelerating...

You should really have it tuned, usually you can get most of the code 3s to go away if it is tuned up correctly. I have never had to mess with the decel air. You may want to try it in both directions and see what happens.
