I just barely installed the comptech supercharger with aftercooler. THe guy that installed it put the fuel pressure to what comptech recommends. I have test pipe, header and dual exhaust.

If i wanted to get the most of the comptech supercharger with the stock pulley, what more can i get out of it with a good tune? and can they tune with what i currently have? or do i need to get a piggy back?

 

Get set up with a wideband to properly set and monitor your AFR for starters, to run safe and as best as possible with what you have. Basing it off a general fuel pressure blindly, is not the way I would ever do it, too many variables. After that, its up to you. Lowering vtec is always beneficial. Timing tune on that low of boost isn't necessary and wont yield any more gains. So all your really doing is investing in afr fine tuning and lowering vtec. If you run more boost beyond what you have, then you will need bigger injectors and have to run some form of EMS to run at all. So with all that, decide on the appropriate solution.
