I really thought hard about leaving it alone and had read in a lot of places that with only 6-8 pounds of boost the stock pump could handle it. What got me a bit more paranoid was when I installed my wide-band gauge and could see the effects of WOT and fuel delivery, couldn't imagine running it up to 6,500 RPM and having a fuel pump not have enough oomph to protect the engine, especially with bigger injectors. I've been working with Jay Greene pretty much and deferred to his judgement on adding a bigger pump, when that didn't work out like I'd hoped I ended up just doing the BAP for extra insurance.
It is pretty similar to the pro-charger from what I can see, although from what I've read it kicks in a little lower. I have a buddy who installed on on his mustang and it is a pretty straightforward setup that gave him roughly 150 more HP, but he also ran it at 10. I don't expect that much, I'd be happy with another 90-100. Until I do some drop in pistons and rods next year I won't push it too hard and just hope to not blow my motor up until then!
With the intercooler, BAP, intercooler tubing, gauges, MAP, injectors and other misc pieces I'm probably all in for $4,500, and the Torqstorm comes with a decent warranty.
