I've got lots of parts ready to fit in the spring; VSRF downpipes, VSRF 7" intercooler, BMS OCC, Forge diverter valves, BMS chargepipe, RB PCV (also LSD, lots of suspension mods, VMR rims, PSS tyres)

I've recently changed the plugs and coils and will be walnut blasting soon.

So with these mods in mind can anyone give me an idea of power/torque once I've had a custom tune (PTF etc).

I don't have access to E85 and would prefer not to run Meth.

Also what would the potential be if running an RB/Vargas turbo setup? Worth the outlay without E85?

Realistically, going with RB/Vargas on pump only is not going to yield much if anything at all over stock turbos power wise. They are nicer built and may last longer without the wastegate issues, although nothing has really been proven with regards to that claim yet.
