something i noticed is that when i go WOT the RPM at 3500 kind of gets stuck, drops a little then goes goes straight to redline. Something like it hesitates. Then boost doesn't stay steady, goes 2 10psi then slowly drops to about 8 and stays there
higher boost will blow the stock plugs pretty fast, depends on how far you go but its always a good idea to base the spark plug choise off what exactlly youre running, any time you change it, your spark plug setup will change for max efficiency/power
how do you explain the sudden drop in rpm and then pick while at WOT?...am i missfiring and then catching???....here's my set up....i have 3.5 inch downpipe...BCC...stock exhaust...HKS bov Vented Into atmosphere...and another thing my boost climbs to ten quick but as rpms go up the boost steadily drops...second turbo kicks in boost rises and then starts dropping all the way to redline...is it the plugs?
