dave xr 2012 Member 2 Member For: 12y 9m 2d Posted 26/03/14 11:59 PM Share Posted 26/03/14 11:59 PM Hey guys I have a ba xr6t ute I've had it since new …. 8months ago I put a bigger cooler on it and I took the middle muffler off …. I have never had any problems till the last 3 weeks … at 1st I thought it was breaking down under load so I replaced plugs , coils etc …. still doing it …. I just had it on the dyno yesterday and its over boosting ….I can't understand why now its doing it , surely the cooler is not the problem …. any other ideas would be thankful ….

Mine was stock though so didn't have to worry about cooler causing it.
