Got my c&l plenum!! I'll try to run tests on a 96gt, worth getting a 70mm TB now??

[96_4.6]

Finally got my C&L plenum and they strongly suggest a 70mm TB or 75mm but OF COURSE all tests were ran on 99+ gt's with the PI heads of course but I wanted one anyway and they claim the main reason a bigger throttlebody provides no gains was due to the poor design of the stock upper plenum. So I'm debating if I should get a 70mm tb, I plan on getting PI heads later proberly much later in the future and I'm running there 80mm MAF and powerpipe and now there plenum so the rule is my heads cant handle that much airflow so a bigger TB is overkill. The mac ones on ebay are really cheap so if you were me would you get the 70 with the new plenum combo or just say you got it for looks kid lol As long as the combo would gain HP not lose I'd be down with it, thanks and also by tests I meant my g-tech lol but I always trust the experts around here
