[QUOTE="TurboTJ, post: 1427381, member: 33074"] Thanks for all the information. I’ve spent a decent amount of time tuning Evo’s back in the day so I definitely appreciate all the detail you posted Audibly, it sounds like unmistakable engine knock which is what has me so concerned. I can’t hear engine knock under any conditions other than WOT at fairly high RPM’s so I don’t know about the lighter load knock (it could possibly be phantom knock). Also, I never heard engine knock on the stock tune. Once I get down to the lower quarter of my tank, I’ll throw in some octane booster to see if the knock goes away and switch to top tier gas next tank. I’ve already taken quite a few data logs with the default parameters. I will post them tonight. Thanks for all the help! [/QUOTE]
