I was looking at the trm chip from racer market. But who knows. Let me know how that chip works out for you.
The supra is also a buddy of mine. Just waiting for a spacer for the turbo flange because the compressor housing is too large.
I'm not sure if I'm boosting this motor later on so I was thinking going standalone like ms or something. I'm in the dark about tuning and know nothing. I really need to read up on it next.
Thanks t.dot for the link. That's where I got the idea from.
