2011 mr
Greddy catback single exhaust
K&n typhoon intake with uicp

So I flashed the stage 1 acn 91 map on my car and it ran fine with no knock at all but it seemed to over boost. I wanted to flash the same map but with the changes made with the intake calibration

So I followed the instructions for the calibration and loaded my new map. When I took it for a ride I could immediately tell the car felt hesitant and when I stepped on it to hit boost it cut out and let out a pretty loud backfire. I immediately pulled over and uninstalled my ap until I look into things further. Does anyone have any ideas what could be going on? Unfortunately I was not logging at the time.

I think Stage 1 is for highflow cat with a catback. Also, stage 1 is not designed for your intake.

Please do not post wrong information. Your statement is incorrect.

Stage 1 is for a stock car catback exhaust being an exception. The intake has been calibrated per cobbs website.

Something might have gotten screwed up when you scaled the MAF/MAP, try this map.

So i finally got the map on to my Ap flashed the map that was attached and the car felt great just cruising around and low rpm pulls. as soon as i try to floor it in 3rd gear once it gets to around 4,000 rpm's it does the same thing and cuts out with a back fire.

I was not logging but I will try to do it again tonight and get a log
