I will definitely be purchasing a U.S.TT, and with fuel, can you explain why I have an option? I just figured since it's a high performance engine 93 was the way to go, although I've heard people using fuel flex b4 but don't know enough about it, other than, it's somehow programed with the ecu.. But you're saying if I use the oem twins that I'm not producing enough air to match my fuel intake with higher boost, causing detonation, or basically that my air/fuel ratio is too lean? If so how do I create a perfect ratio, does it depend on my boost? The AEM Tru boost controller comes with an all in one gauge and from that, I read it's highly recommendable. And yes definitely aware that a cat-less downpipe makes more power but I read its only a difference of like 12hp, and with emissions and all, I'd opt to still possess the legal high flow cat..Also can you please explain the adjustable exhaust cam gear, in relation with TDC and if that will help prevent pre-ignition or detonation? And I read somewhere that the Paxton fuel system was popular among Supra owners that why i mentioned it.. The thermometer I mentioned because I read that increasing hp past 500 hp would require an upgrade to the whole fuel system, including the water pump and thermometer etc..Also can you explain the difference between the 4 speed auto ECT to the 4 speed ECTi? I read it was optional on the autos, but don't know when n why it became an option, 93-98? Thanks! Love Supra's and want to know everything I can so to approach my ideal specs.
