Thanks Suhail, think I have it figured out as I have two routes of testing, rewiring the 07 pressure switches or weld a new pressure transducer and re-enable it on the cal so the system would work as in a 11+.

Any time my friend

One more thing you have to worry about is the idle controller when you turn the a/c on rpm need to go up. Man I had a hard time with that

No issues here as the PCM is controlling the system so the AC flag comes on and all the airmass adders work as stock.

Ok, sorry for the delay, I was roaming around the US until this sunday and I had left the file here so could not publish anything until I came back.

Car made 366/373@6700/4400 SAE on our dynapack, numbers seem low but are in line with what we expected, for example, an intake/tune manual stock 3V would go around 270 in our dyno and not close to 300 that I've seen in the dynojets, correct me if I am wrong with these numbers.

AC issues have been solved by changing something in the calibration to delete the pressure sensor and route the clutch activation line thru a relay that works with the stock pressure switches, we have AC cycling as expected and all.

Dyno graph is attached.

Car has had changed the gearing from stock 3.31 to 4.10 and we are waiting on some parts to install the 2.9L whipple and T56 magnum in it.
