The Mach 4 is an excellent injector, however, in my experience they have been a little hot towing down low with a single charger. Now to add to that, the truck we had them in never had a great single charger and a HRVP44 as well. Also it was an auto, that was gear more towards racing. We did try running it with a USB, which is a 62mm s300 variant, much like the htb2 with a 62mm wheel or the II turbo you are currently looking at. There have been many improvements to the s300's since then which should help with spool up, and reduce low end heat, also the fact that you have a manual, should help in giving you a little more control.
However, we weren't towing that much weight, and a lot of times we'd have to back out of it, or manually downshift the transmission, and back out of it a little, on hills, which made towing kinda lame. Don't get me wrong, I'm not trying to steer you away from this combo, just be very careful in selecting your exhaust housing and wheel, to get the best for towing. I'm a big advocate of the turbo bouncer is running, the 62/13 with 71mm ex.wheel. That seems like it will spool well and be a very nice towing single with some good top end potential.
Also, don't stack the Edge with the Superchips when you get the edge in, either ditch the superchips, or set it back to stock and keep it only as a code reader. Combine they will be too aggressive on the timing.
