Will using the velocity stack adaptor that treadstone uses work with the greddy kit and pretty much be the fix that the ecu can't provide? Atleast for everything but w/o throttle? If anyone thinks it'll work or not work tell me. Also if I didn't buy engine management, only bigger fuel injectors can someone tell me how bad of an idea that it. Would it be way to lean?

 

No. It's not that simple. The velocity stack had to have been tuned with the turbo kit.

And I would worry more about the ECU tripping out with that velocity stack adapter than with an Emanage. I've heard of those things all of a sudden forgetting their tunes on Toyotas but it hasn't happened with anyone here yet. Tune it electronically.
