Whipple supercharger 98 5.7

The Whippletronics computer is crap. Get an 0411 computer and tune it properly. The only issue on the vortec is you need a higher output spider (wynjammer has them) or switch to a marine intake AS RARE AS A PINK UNICORN (what I would do).

Thanks for all the replys. I am still new to superchargers. I have read about marine intake manifolds was not sure how big a deal it was to install one though.

So I had Justin at Black Bear tune my ECU for the supercharger. After I had my tune I ran my after tune logs and sent them in to him only to find out that I am having some fuel pressure trouble under boost or WOT. I hooked up my gauge to my fuel pump to check the FMU and at about 5# of boost my pressure will jump from about 57 psi to 80 then fall to about 72 psi I am not sure if it's my FMU or my stock fuel pump can't keep up. While I was searching for answers I found where a supercharger on a 454 was blowing out the spark and he replaced and gapped smaller. I just changed my plugs and gapped them to factory spec could this be a problem ? Any help will be greatly appreciated.
