Turn down pipe and retune
Had my car retuned after figuring out that my exhaust was holding my 6466 back on the initial tune. I added a turn down pipe at the down pipe and removed the rest of the exhaust. and walla almost 90whp/40tq gained adding a few more psi.

Thanks Tom, my tuner kept her pretty safe for what the boost levels are. 11.6afr and 14* timing. Car runs smooth. 10.4@144 loosing my accessory drive belt mid pass and it felt like I hit boost cut when I lost power at the top of 3rd.
Turn down for what? Power
I had similar results with my exhaust setup. When I drop my exhaust from the downpipe, I pick up 50whp consistently. Boost goes down a couple psi but power goes up, sure sign of restriction.

Ya thats how my car is. it peaks 12* at 8000RPM. mines really conservative. Yep you lost your alternator power, so im sure your tune was instantly affected by that.

Great power and that color is awesome on an EVO.
What was your exhaust setup before you removed it?
How do you like those hoosier drag radials on all 4? I had them on a rwd car and they did work.
