If you want your car to run right go email AED
Lol right .. but but his toooner said .....
Oh oh oh that's right he really knows these cars lol. But no one of these forums have heard of him. Just like another thread floating around herem
The internet is full of people who read, but not everyone is on the forums. Just cause the "forum" does not know his tuner, does not mean the tuner is not "good" or "safe".
hitting rev limiter maybe?
I would datalog to determine if its engine or trans related and go from there. Try shifting at 7,000 and see if its still an issue
Buzzing sound at high rpm's?…Detonation maybe??
What bout fuel cut? Possibly causing the issue? I cannot remember where they are set at factory. Maybe he missed that adjustment. Also don't bother with these guys who are negative. Any time a tune comes into play its aed this aed that. I know shaun is a reputable tuner and does good work but that doesnt mean that everyone else is garbage.
From the sound of it, it's TiVCT reverting back to *base* between gears, causing a noticeable change in exhaust tone and a drop in power.
Or just let AED reach out to you... I haven't even taken my morning poop and Shaun is diagnosing vehicles for guys he didn't even tune.
Not trying to derail but THAT is why we all recommend AED. Not because others are garbage, but because we believe AED is the best tune backed by the best service. Good luck OP this stuff is over my head.
