Current port offering is the Too High PSI setup. I've tuned a bunch of these and its not difficult. If you want to wait a little while, DSX is coming out with a port setup that will be easier to tune and not require a separate port controller.

I ran the stock in tank pump with the Toohighpsi port injection along with a 2300 Maggie I got used from Superchargersonline. Made 707/669 on E65. Its the easiest hp out there in my opinion. I think its still a ways off on the DSX release. The THPSI is a proven product and you can get it now. I did run the JMS boost a pump to help out the low side, but not sure I really needed it since we actually ran the low side at about 60 psi and the high side at about 2200 psi. Never had a drop in PSI on the low side and had plenty of fuel on the high side. We did run 9.80@142.96 on that set up. So, Megahurtz and King have it right, save some money and make great power for the street and track.
