I recently bought the Accessport from cobb this week. The first day I got the AP(thursday) I put on the stage 1 map(I have nothing but a SPT exhaust at this point). The car ran fantastic. This morning I put on the Cobb down pipe with the Highflow cat and realtime tuned it to the stage 2. I took it for a spin and it wouldn't build boost past 3 to 4k in 3 gear on. Then I thought I messed it up because i was suppose to reflash instead of the realtime. So I went ahead and reflashed the car to the stage 2 tune again. Same problem still occurred, so i uninstalled the accessport and left the downpipe on. It still doesn't build boost past 3 to 4k and the car stalls sometimes if I pop the car out of gear. NEED HELP…. not sure what is going on.
