I have an auto + TTC, but we did the extreme TTC by following the secret sauce link:http://www.supraforums.com/forum/showthread.php?199001-MTR-s-TTC-secret-sauce-mods....pics&highlight=secret+souce
TTC lag is overrated imo (but also very subjective ). The only time you will notice it is on WOT after you have come to a complete stop. When cruising around, boost is available 1 or 2 gears down
Next year (feb/march) we are doing a manual conversion and I will post de dyno figures.
The following is part of the 'TTC secret sauce mod' and removes all butterflies between the twins and exhaust, which had def. made a big difference:
1. #2 Turbo Pipe Mod - remove the butterfly in the pipe coming off the second turbo. Then take a digrinder and remove the aluminum arc that went around that butterfly. Also get the hole where the bullerflys rod came out of the side welded up. Now another thing that you can do is take the middle plate with the openings in it and swap it out with solid piece that you can make out of 1/8 inch aluminum. This is the piece in the picture with the gaskets and crappy blue sealant on it. This plate that goes on top that makes it so the air doesnt have to occupy the extra area in the upper part. Also makes things less turbulant.
2. EGCV Mod - Take out the stock EGCV butterfly and replace it with a straight through design. You can just take a screwdriver with a hammer and bash out the butterfly but that leaves the rod which I also wanted removed. The reason why you need to make an entire new piece is because the stock one is made of ceramic. And since you can't weld ceramic, you would have two large holes in your exhaust. I made mine myself on a lathe out of a piece of temp resistant steel. This will increase the crosssectional area of the #2 turbos exhaust by over 30%. Kinda a pain to install but I found it to be worth it.
