With my present FI set up I am estimating about 640 - 650 whp.

With the addition of LTH's and a proper tune revision, what is a realistic gain at the wheels?

Are you going from stock to free flow or aftermarket cats?

No emissions check in my State. So I can essentially run "off-road" LTH's. I have a 3" Thermal R&D axle back now with the stock exhaust manifolds and cats.

LOL. Dancin’ with the Devil huh?
Always! I was close with uncorrected numbers and just a Roush P2 kit.. 667 :p

Curious what my new car will put down now that I *do* have headers and also a tune.

Dammit.... We are all wrong! He asked what kind of "GAIN"... I'm revising my answer to 26-16! :p

Stock manifold and cat to LTH without cats 40-50hp
