which tb is best for me?
hi i have a 2002 ls1 engine in an rx7 it has ported 853 heads, crane cam, 1.8:1 rockers, dual valve springs, tubular headers, ls6 intake and currently standard maf sensor, throttle body and ecu, it made 440.4 hp and 492 lb ft. I am planning to go with a stand alone ecu which will not use the maf sensor so my question is would i benifit from a tb change? if so which one do i go for a ported original or an aftermarket one which would be best?
Thanks
matt

I had my stocker ported. I gained some throttle response. I also have a aftermarket TB that would idle on 2500 and then slowly set back down. So I'd say port the stock one you'll probably pick up a few hp.

You need to adjust the idle screw until you get the idle where you want it within an acceptable IAC count range (probably why your car is hunting for idle is your IAC motor is counting up and down to get the idle where it needs to be). Then once you get your idle set with a decent IAC count, you need to reset your TPS sensor.
