Just got back from the dyno again. New setup is a ptuning turbo kit with the gtx3076r. Old setup was a trackforged manifold with a garrett gtx 3576r. New setup made 425whp 293tq on 91 octane at 13psi and 588whp 419tq on e85 at 20psi. I lost about 25whp on pump gas and 35whp on e85 from the trackforged gtx3576r setup but i gained about 300 rpm of spool and a lot petter boost response.

Full engine mods are

Hell yeah man, ever thought of taking it onto the smokingtire with Matt Farah?

 

About what was expected. Not much change, but more in torque due to the smaller exhaust wheel. Compressor wheels between the two are the same.
