Bought Hellion kit for 01 COBRA need some pointers

I just bought the 03-04 Cobra 76mm kit. I have a 03-04 Cobra fuel tank with Kennebell BAP, 60 lb injectors, SCT 2400 MAF, and fully built Shortblock. I had a Procharger D1SC that made 530rwhp on 14psi of boost, but I sold it for the turbo. I'm going to try to limit the power to under 600rwhp, because of my fuel system. My main concern is tuning, how reliable is it on the street, does it have MAF backwash issues, stalling while coming to a light or stop, surging. Any advice on the tune. How does a turbo driven car differ form a Centri blown car.

We've done a few and have had excellent results with every aspect of the kit.

What size turbo did you get?

Were you running the procharger draw thru?
I switched my procharger setup from blow thru to draw thru and got a ton of surge problems.
My turbo setup is blow thru and has zero drivability issues. There is a huge difference between a centifugal and turbo in feel. The turbo torque hits really early and just stays. My setup uses a pair of small turbos so it is at 10 psi really fast. With the turbos, the more the motor is loaded, the more the turbos come on, with the centrifugal, you need to get some revs going to get alot of power. I think you get a good bit more part throttle power on the turbos too.

Where the surging comes from on the big Procharger setups is from MAF reversion (usually). This will not be a problem with your turbo setup.

We can do a tune for the car that should be 99% spot on, enough to where you can drive the car safely until you can either get to a competent tuner, OR you can get us some dyno information so we can make the necessary tweaks (if any are needed).

Depending on the placement of your bypass valve and where you have it vent back into the blower before the discharge pipe, you can have air start flowing backwards across the mass air meter if the bypass is filling up the pipe.

The kit is VERY streetable!
I have been on a few rides in the Red Fire cobra featured on the hellion site. With the 76mm it was a very smooth car, I think it is often daily driven
