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?

There are alot of factors that it could be....one that im thinking is a blocked cat or something like that, or check that your not having a boost leak sumwhere, so check the crossover to throttle body, and other cooler connection pipes.

If your not far away from your tuner u could take it there and put it on the dyno for a better diagnosis.

Need a few more symptons here...

Is it missing up high? How high? Under what sort of load?

Did you do anything else besides replace the plugs? Did you gap them correctly?

Could be coil packs if they are still original in a 03 ba, had the same car myself. Defiantly worth a trip to a tuner for a quick answer rather than replacing bits for shytz n giggles.

mine did the same, would only hit 10 psi anything more and would stutter, or brake down.(would still go to 6k not under boost) Did plugs, not much better so got a set of supposedly genuine ford coils from e-bay for $170ish

fitted them in 30 mins and all good to go. Dunno what tuners cost but this may be something you may want to try first. wont hurt. :icon_ford:
