The bummer was that the operator shut me down for being too lean while I was A/Bing the SMT and my spark kicker.

Yea pritty much intake and exhaust is the only thing you can do as of yet. (headers and cat back will yield something)....hopfully cams will be an option in the near future.
Even getting a piggyback like the smt6 that can control fuel and timing will yield some power increase it depends on the engine but I have seen up to 20hp increase
I plan to try doing this on my dads 93 4runner with the 3vz-e 3.slow

the 3vze is easy bigger injectors upgrade your fuel lines from tank with -6an and cleanable filter on outside of framerail with a banjo bolt adaptor straight to the fuel pressure valve on the rear of the passenger side rail and a egr/pair delete and I’ve honestly gained over 100whp in my 91’ 3vze! I’d say almost as fast as a stock 3.4 which I had in my 96’ Tacoma. But once I put bigger injectors in and bigger wires and k&N intake that 96’ was a force to be reckoned with! I’m bout to start again cause I’m in the way to buy a 99’ 4Runner 3.4l! Next will be a 2jz swapped 91’ short box 2nd single cab pickup with 4link and cage and awd if I can get it out of a newer Toyota!
