How are you hitting that 5-600whp mark? Is it just a turbocharger and fueling that will make this hit that mark? Are you worried about turbo lag?

I plan on adding a centrifugal supercharger to add 300-350+ whp. For fueling I'm going to use port injection with fuel pressure regulator , high flow fuel pump, and a return line.

Sorry, these questions might sound stupid but are you going to be running ethanol mixture with that fueling upgrade? Whats the point of the fueling upgrade? I am trying to figure out whether or not you need upgrades to run ethanol mixture with stg1 and cp upgrade only.

it's cool with questions we all learn. The reason for fueling upgrades is because the stock fuel system won't support the horsepower I'm aiming for. I live in north NJ and I can't find anywhere close to get e85, so my plan is only to use 93.

I am also in NJ and yeah its all 93 around here... but you can just mix it yourself, although I guess that comes with some challenges.
