Was speaking to Regal about there Phase 3. Mentioned about other bits and they said u cannot really get much more than 270bhp about of the Z20LET because the exhaust manifold is a big restriction? But what they did say is they have developed a new one which unmapped but using the P3 software will be around 330bhp and I think she said 360ftlbs torque but they still need to make a map for this software. Anyone else heard this?
This is with the P3 setup also
