I know that tpis is actually a ported edelbrock base, but how much more of a gain will be noticed from the extra porting? Is it really worth the extra money. I was planning on slapping on a 52mm throttle body and an AFPR while I was at it. Also, what do you guys have your fuel pressure set at? I know that fuel pressure is different for each individual setup, but what would be a good starting point for my combo-in my sig. Thanx for any help.

TPIS takes an edelbrock base and port matches the base to any size intake or runner gasket size you specify. If you do no feel like porting the edlebrock base yourself and feel like paying an extra $150-$200 get the TPIS and just bolt the base on.
