Decided to part with the Dinan software. Pretty glad I did, BPC squeezed an additional 22ft lbs of torque out of it.

I'm sure there has been mention of it in other threads here or on other forums, but I Have come to understand it's the difference of a tune that's safe for the masses and therefore conservative Vs. A Dyno Tune where the A/F ratio can be monitored real time and timing, fuel, etc. can be adjusted to make peak HP/TQ while maintaining temps and A/F.

That's not to take away from all mail order tunes, I believe the consensus is the Dinan software is a bit on the "conservative side" when compared to others. Even so it was a noticeable difference from stock.

I'm very happy with the tune. I've logged a little over 200 miles with it so far and it's an obvious increase in power in the lower rpm.

Those numbers are nuts. I forgot about the headers for a minute. Guess the lack of cats is a pretty big deal!

cats can still bring big numbers, if they are high-flow units. magnaflow makes some decent all-metal substrate units that flow really well.

but yeah, headers - no wonder those numbers are so good. look at that torque curve - so flat. even gains across the powerband.

you are fortunate that that shop is fairly local! it looks like they do remote tuning as well. hmmm...

It's like two hours from me, so when you iron out a good catted header solution, I'll copy it then head up there and guinea pig their tune.

Makes me want to install some headers now.

magnaflow makes some high-flow catted headers. they are expensive though... i think $1600.

Went out early and did a few drive cycles with the BPC tune to set monitors. Took a few cycles but it set everything. Now I can renew my plates. 55mph on i540 is slightly uncomfortable.
