Evo feels like its falling on its face under boost at WOT? Spark plugs? boost leak?
Well i know that im only sup to run ngk iridium spark plugs, but i just bought my stock 03 Evo VIII and did a tune up. I checked the spark plugs and found some champion iridium spark plugs. Are they ok? or what spark plugs should i get to replace them for my stock setup?
Anyways here is my problem, when im at WOT and under boost the car feels like its falling flat on its face, its just not wanting to go anywhere and when i let off the gas just for a sec and punch it again it take off! WTH? Im thinking it might be the spark plugs or they have the wrong gap or it could be a boost leak. Im wanting to do the boost leak test but im waiting on my 2 1/2 inch coupler to get here in the mail so i can performe the test. Anyways, please let me know what you guys think, thanks yall ahead of time
Here are some pics of the Spark plugs when i chacked them out ( sorry bad pics, i didnt have my cam at the time and i was using my cell phone )

Dude, I would not use any other plugs other than NGK. As for your issue, I think you probably didn't tighten the intake coupler. I had the same issue the other day at a race and I knew I didn't tighten the coupler that goes on the turbo inlet. Tighten that sucker today and she runs a lot better. Could have won the race but I loss to another fellow Evo. But yeah, change those plugs bro.
