Didn't realize they did exhaust port manifold work...I think I'll get a manifold and send it over to them. Everything else is in place on the car, this is it for engine mods for me (famous last words).

Some more impressions...
I live at the top of Highway 84 (for those that know the area). I've driven up the hill in 5th gear! No, it's not a dragster at the less than 2k RPM range, but it has enough pull to get up the hill...
Also, on some of my friendly twisties, I had to TAKE MY FOOT OFF THE GAS otherwise I would have been going to fast. And this was at a section where I'd just leave it floored before....
I did one G-Tech so far, and it was almost 20 HP better, but the statistics aren't there, and it was a cooler day, so that's not a number I'd say is accurate, more a guide to the eye.....
So far, so good!

I’ll share my unsolicited long term impressions. ENDYN big valve head optimized for mid-range rpm performance, stock camshaft & springs, ENDYN ported & port matched intake and exhaust manifolds, ENDYN ported SC with case & lobe coating, 19% reduction pulley, 380cc injectors, GIAC/Helix flash, hand ported, port matched & short side radius polished supercharger and intercooler output ducts, with stock intake.
At the dyno (Mustang, 101F day) with Milltek catback, 41.50 lb-ft torque and 58.81 hp over stock base line, that’s a 37% increase in torque and 48% increase in hp. I exceeded the former peak torque way before measuring started and later torque peak only dropped by10 lb-ft at redline. A/F ranged from 11.2 to 10.4, avg. 10.8. On a Dynojet the torque curve was flat from 3200 to 5400 rpm with very little deviation before (8.4% @2,400rpm) and after (9% @6,400rpm).
On the street with Borla standard catback, power and torque are supplied where I use them the most; roll-on passing performance and drives out of curves. I don’t need an aftermarket intake and I don’t need a turbo; there’s little I’m in want of under the hood.
