Hey guys! I had my car up at Buschur Racing for the past few days, and here are the results. Remember this is on Dave Buschurs Mustang Dyno:

While it is here I told him if he wanted I would look the tune over for him if he wanted. I tuned it when it was brand new last year. The car is a 2005 RS.
Car is equipped with our Stage 4, alky kit, AEM EMS and GT35R turbo. Engine and head are stock.
Last fall the car made 365 whp and 278 ft lbs of torque. I don't still have the logs but would guess this was around 25-28 psi of boost. I am sure Keith will chime in and he will remember.
Today I started tuning the car and it only had about 18 psi, this is how Keith brought it in to us. I was surprised to see it make 350 whp without trying at that same boost level.
Keith wanted me to hook the alky kit into the AEM for some added safety.
The freaking car is amazing. It is HOT here today and I am running the dyno uncorrected. Had I turned on the SAE correction it would have been even higher.
Ended up making 452 whp and 362 ft lbs of torque at 28 psi of boost. This is a gain of 87 whp and 84 ft lbs. The torque is basically a flat line from 4900 to 7,000 rpm.
I always leave the AFR's rich on alky and this car was no different. 11.0-11.2 AFR's all the way across.
All we did while it was here was install an new Exedy clutch and put our new V-band 3" turbo back exhaust on the car.
I am very impressed. What do you think Keith?!!
Here is the dyno sheet:
