Assuming you're running a 12A, the only way to decomp the engine is to find 12AT rotors, which you guys got and we didn't. However, you do not need to decomp, you need to be much more careful about tuning and not run as much boost as one would with the turbo rotors. Higher compression rotors will produce more hp at lower boost levels, but can also detonate easier.

Timing and afrs are crucial, find an experienced tuner.

 

A T3 is too small for any rotary let alone one with a bridgeport.
