id say go with an EWG instead of spending money on meth. Like ugm said, get it ported/polished. Definitely helps. I also don't see why you need an "aggressive" protune. You will only be making like 5-10whp more than a safe tune and you will be running a much higher risk of blowing it up. Like in my car I had about 15whp on the table but snowman knew what I was using the car for and made sure that it ran 100% without blowing anything up. Car had 30k HARD DRIVEN miles on the engine and it never skipped a beat or burned a drop of oil.

....until the fire burned through the external oil cooler hose, then it burned a lot of oil
