Hey guys just picked up a paxton novi 1000 just was recently rebuilt w 30lb injectors 7 and 10lb pulleys and c&l maf.. With a good tune about how much hp gain should I expect on my 03 gt it's aod car mostly stock exhaust is about all that's done to it.

 

I say 380

 

That's ab what I have in mind.. I have a new set of ford racing 373s that I haven't installed yet.. Would I be better to install them or get some 410s? Again it is an aod car

 

With a super charger I'd say 3.73. If you used 4.10's it would be near impossible to get traction.
