STYLZEE Member 75 Member For: 16y 8m 19d Posted 22/07/10 04:13 AM Share Posted 22/07/10 04:13 AM Hey guys,I have a 2003 ba xr6t and when it hits boost at high revs it looses all power. The spark plugs were dead so ive replaced them which improved it a little bit but its still loosing alot of power. Any ideas?Daniel Link to comment Share on other sites More sharing options...

Under what sort of load? Did you do anything else besides replace the plugs? Did you gap them correctly? Link to comment Share on other sites More sharing options...

Defiantly worth a trip to a tuner for a quick answer rather than replacing bits for shytz n giggles. Link to comment Share on other sites More sharing options...

Dunno what tuners cost but this may be something you may want to try first. wont hurt. Link to comment Share on other sites More sharing options...
