any one experiencing a slight hiccup in 4th and 5th gear only at peak boost when stabbing the gas.
doesnt feel like a cut not that ive experienced a cut to know for sure? just curious to know wether i should slightly raise my boost limit function to confirm wether or not its a cut. obviously i dont want to increase the boost, just the limit in ecuflash to confirm if it is indeed a cut.
car is mostly standard has new plugs and just an aftermarket manifold and 3 inch cat back. havnt done any logging yet but can do if someone thinks they can help

sorry should have mentioned its a jdm evo 7 and running new br8eix (i think) plugs

whats the general concensus on items to log when diagnosing these types of faults?????

A "slight hiccup" is not boost cut. A "holy crap I almost went through the windshield" is boost cut (fuel cut)

I would lean towards plugs if it's a slight hiccup right at full boost. (worn or too large of a gap)

What is your gap set at and what type of boost level are you running?

So if you want more help we will need the gap of the plugs, boost level, and a few 2500-7100 rpm logs to see what is going on...

Probably gapped too large as they usually are out of the box. Gap them to around .024-.025

If you pull on the actual plug wire itself to get it off the plug you can damage the plug wire. Its next to impossible to see and will give you fits under heavy load. I did this to my car and from now on out i pull on only the rubber boot no matter how stuck that BEotch gets
