For those of you wondering how much of the torque dip was elminated here is a plot with one of hte stock roms with the OEM header. I flashed the stock rom with the advanced multiplier set to 1.0 and did some constant load driving for 5-10 minutes and started doing pulls. It was losing power every pull. I pulled one of the middle pulls. This came in at 128WHP. The lowest I got was 124WHP and it was still losing power on every pull... I was guessing it was going to land 121-123WHP with the stock rom after learning fully kicked in. I figured I would just get one of the middle plots so that way it doesn't look like I am "fluffing" my numbers up. The torque dip was basically cut in half. The header gave a weird torque bump at a really low RPM making the illusion of the torque dip even worse (but in reality it just had an odd resonance gain at the lower rpm??)
