theres virtually no benefits in upgrading to the GTX on the stock engine, look at the compressor maps. the gt2860 is good for about 580-620whp @ 18-20psi on pump gas with our engine, you could run a bit more boost with meth or e85 but its starting to overspin the turbo and will shorten its life.
if you were planning on running more than 20psi, thats when the GTX really shines, on our engine you could easily run 25-28psi on those turbos without going past its efficiency range, they are good for about 650-680whp. its like getting the response of a gt2860 with the top end of a gt2871r.
