Loss Of Power At High Revs In R33

[boostn0199]

in my r33 gtst, i recently had got missfire problems on boost and I changed the coil packs to splitfires and changed the spark plugs aswell while i was at it and now missfire has stoppd but i feel like im not getting as much pull as I was before at over 5000 revs. any ideas

no replies? im having a similar problem. Over 4000/5000 loss of power then power comes back on at 6000. come on guys help us out

just a stab in the dark but does the boost rise and fall maybe the boost controller or vacume leak maybe the tune even are you running standard ecu?

I had a simular problem when i put the wrong spark plugs in with wrong gap. As soon as I put the correct one in with correct gap it was boosting how it used to around that rev range. Just a thought.

bump...im curious about this one

[NARTRI]

have you checked over all your pipes and vaccum hoses might have one that is not tighten correctly or lose?

similar case at one stage one of my pipe wasnt correctly tightened after i have taken it out

what heatrange plugs did u put in? also what ecu and mods do u have?

WALLAS: your problem sounds like classic Rich and Retard if u have the standard ecu?

Do a ecu reset and check Base timing.

Check boost to make sure its under 10-11psi.

Do give more details of the plugs you used.
