sorry dude, have on idea what your talking about. more info

flangemastermike

well kinda said it all ,but its only one cracking noise , sometimes 1-2 crackin sounds, doesnt sounds good , dont want to drive it. could there be slack in the cams or pulleys or belt ??.

Sounds like a flux capacitor issue

flangemastermike

Damn those flux capacitors!. really stumped though.

Check valve clearances possibly?

Check your getting oil to your turbo? I had a simalar thing on my first turbo d16 setup it sounded awful it was just my t25 running without a good enough oil feed.

I cant think of much else, maybe do a compression/leakdown test to make sure or...

your catdaddy switch may not be terminating the harmonic value of the proprietary induction at the proper miles per gallon. check that, or the muffler may have a leaking main constrictor valve which is causing your wastegate to deregulate the wholesale fuel consumption causing a glitch in your transatlantic revolutionanary junction. hope that helps

flangemastermike

yeah will check the valve clearances tomorrow and belt. think my main constrictor valve is good and the wastegate sure is deregulating. if any one else has any clue im all ears .
