High RPM miss

Guys. Went out last weekend for some drag racing and on my second and third run, started having a mild miss around 5500 Revs at WOT. Am thinking plugs which I'll be checking shortly. Any other ideas are welcome.:smoker2:

Yepp, that would be the first thing I'd look at - plugs.

If your running higher than stock boost, reduce the plug gap down to 0.8 mm.

If that doesn't help you'll have to do the usual thing of checking the coils, AFM, TPS blah blah blah.

Good luck.

I gotta miss at 'bout 6600 revs in fourth gear at 190 clicks. :jump:
Wire 53 fixes this one right? Oh, BTW is 53 written on the wire, how do I know which one it is? :confused:

I had this problem, turned out to be my shift light somehow mucking up the signal to the computer. Disconnected it and all was sweet again.

Hi R33injp,
also check your fuel pressure, your pump may be failing.
