Brian, Yes CHE is castle hill exhaust but we are chainging names at the moment we have been beta tesing the ford VCM software since Dec last year, so far all results have been very promising. peak boost is the same around 3500rpm and 13psi but after that there was some adjustments done to the boost with boost now holding 11psi not dropping back to 9psi like the previous tune from memory on the same boost it went 284rwkw. I didnt tune the SCT box, they were done somewhere else in sydney.. I have attached a sheet with boost on it, ill post a compare between the 2 on monday and one with the boost at the same levels.
