@HeresMyMind is that a standard/non-modified OFT stage 2+ 4.03 off-the-shelf ROM?

Torque Dip is completely gone, replaced by small bump at around 4500 RPM!

Completely unmodified.

The run was also after the IAM got up to 1.0 after a few light pulls.

My mods just Happened to be the perfect combo for this flash.

I may be able to squeeze a tint bit more power by leaning it out to 12.5 afr average but the 11.9-12 is more on the safer end. Especially for a generic map.

you could do that in few minutes with romraider just few logs to see if it knocks, if all goes well you could have a bit more power and better fuel economy

not bad, would be interested to see a stock comparison.

Also +1 for doing a ecutek comparison.

i have a custom oft tune, but have been thinking about getting a custom dyno ecutek tune.

Wow very nice - just a quick and dirty comparison, torque gains around 20% in the 3000's. Then around 10% average between 4000 and 6000. And then great gains on the top end, peak gain of about 24% near redline. All with a 'canned' tune.

But wait, this can't be right. I just read on here that the only good header out there was the $1400 ACE? Everything else was crap with torque dips.

I believe ACE is the best header for all around results and being EL.

Most EL headers still have the torque issue. The only one I've seen that has a flat trq value are HKS EL's. Although I dont think they have the best overall gains. Check out these results.
