First off my car is a 2003 "G" 6MT Coupe.
Mods:
TechnoSquare Crawford Reflash ECU
JWT PopCharger with "Z" Tube
Crawford V4 Plenum
Crawford HiFlow Cats
Crawford Headers (Aint that what this thread is about?)
Invidia G200 Dual Exhaust with "H" Pipe
Ground Wires
Well - Had some fun last night. My Speedshop, Apex Motorsports in Tucson, finished my install last night. As everyone says, it's a real tough install, but IMO, well worth it.
As luck would have it the guy who runs the Dyno at Apex, has a 2005 "G" Coupe 6MT. So here's a guy with the new 298HP engine with the new cams, exhaust timing and bottom plenum. His only mods are a K&N Filter, "Z" Tube, and Ground Wires.
It's a warm night here in Tucson, about 94F, so horsepower levels are probably a bit low. Anyway, he stuck his car on the Dyno does three runs, and he has a range of from 236 to 242 horspower. We then do a switch and add the Motordyne 3/8" Plenum Spacer. This is the first one I've seen, and it is a real stealth mod. He wants to see if it works. Does three more pulls and he gets 248 horspower for each of his runs. So yes, to put all rumors aside. I saw exactly what he did. Six runs back to back. Plenums do work on the new engine.
Now for the exciting stuff, for me! The techs are just buttoning up my up may car, and we all want to see how the old modded engine, does against his new 2005 engine. So I start up my car, sounds great BTW, and drive it on to the Dyno. The modded ECU is reset, because the battery has been disconnected for and day and a half, so it has not relearned my aggressive driving habits.
He drives my car on the Dyno, 3 pulls. Results all exactly the same. HP and Torque are corrected SAE. I've attached the results My Lines are Blue, his (the 2005 with the Motordyne) is Red. We peak about the same 248HP, but I peak 7-1/2 pound feet of torque higher then him. And if you look and the curves, I beat him in all the power ranges up to about 6300 RPM, where the new plenum runners and cam take me by about 1/2HP. I was hoping for a run of 250, but what the heck. See Graph attached.
My ride home was great. Those headers, are the most significant mod I've done. I can really feel the kick in the butt. I should have done this long ago.

No, Crawford does not make an ECU. Nor does TechSquare. TechnoSquare has decoded the stock ECU, and can reprogram it. Crawford and TechnoSquare collaborated and developed a new program for the ECU for use on Gs and Zs with Crawford Equipment. TechnoSquare does the reflashing.

Did you get to capture the A/F ratio with the dyno runs? I have been having issues with my car running way to rich with the technosquare "Crawford" flash and TS just can't seem to get it right. I am looking at the 5th reflash soon 
If this next one doesn't work I am going to a limited flash and getting a piggyback system for tuning. I do have additional mods and have a 5AT so this is in no way Crawford's doing, that just happens to be the flash we started with since I have their performance parts. It is also amazing what being rich by 0.8 can do to performance.
BTW, the headers look great and I agree that to date they were the single best improvement in performance I have done to my car. The crawford plenum being a close second.

No, I did not get my A/F Ratio. But, I don't believe I am running rich, because I am not leaving black residue on my tail pipe tips.
