Dyno Run
#11
I second the 6port option. On my 90GXL, the most I've dynoed has been 115rwhp, this is with 2.5" header->presilencer->ypipe->ebay fartcannons. Turns out that my 6 ports were not opening, because when we unhooked the tube to the cats, the air was too free-flowing to open the ports it would seem. I wrapped a large bolt in electrical tape, and hose-clamped it in the rubber hose off the back of the intake manifold that normally would run to the cats. This was just a little bit ghetto, but I think it helped to unstick the ports, as it fell out a while ago and I still have power over 6.5k (where it used to drop off). I'd double check that they are working, if you have another dyno day comming up, see if you can wire them open for one run to see if the top end improves.

Dude what day was that, you should'a called me! Hopefully I can get my problems ironed out and dyno my car soon. Are you gonna dyno tune or seat of your pants tune? Should probably dyno-the average person doesnt have a very well calibrated ***
