Hi mate, I have a BF XR8 with 2.6 Kenne BF XR8 KenneBell.tecBell blower on it. Stock engine with billet oil pump gears, it makes 385RWKW/ 343NM on a conservative tune.
I am not a tuner and originally it was tuned by a reputable shop with SCT tuning software which I later read then re-flashed using PCMTEC.
The PCMTEC software attracted me because of all the parameters you can change for drivability as this car is a daily driver as the SCT software is pretty basic.
As Puffwagon says, the ability to look at stock Ford files is handy as I used this to fine tune my Ford twin throttle body settings using an FG GT file and the Tip In Retard settings from an FGX Sprint to fine tune a dead spot when mashing the throttle from low revs as well as many other small settings for smoothness and drivability.
I'm running 11.8 pounds boost with Bosch 0 280 158 279 injectors and an Aeromotive 340 in-tank pump and from memory had 57 psi of fuel pressure on the dyno before the stock regulator. You will also need a decent exhaust system. I was recommended by Blue Power racing to fit a twin 3" system with 1 7/8 four into 1 extractors not only for increased flow under boost but also to help scavenge exhaust gases out of the combustion chamber so as to run more ignition timing.
As I said, I am not a tuner and have not touched any of the main fuel and timing curves that were set on the dyno except to tidy up a bit of low load and idle timing. I have attached a copy of my tune for you to look at and give you some idea on where you should be heading. This car has been a daily driver for the last 11 years with this power level and tune and it has been ultra reliable and idles like stock. I think the hardest thing to tune, from what I've read on these forums, will be your cams and you may not need them given the power and torque available from the blower.
