Want to run more boost on VF setup
Am running a vf570 setup with upgraded SI trim. Am hitting 7psi on gauge tho dyno reads close to 10psi. Am hitting 470whp 91 oct only in 5th on dynopack. 500 whp with 91+meth
I would like to run a bit higher boost as I have a 5 gallon tank for meth. The options are upgrade from 2.7inch pulley to either 2.62 or 2.4.
