Boost A Pump at one time from Keene Bell was very reasonable. You may check there. The tune I would look at Allen Nelson at NelsonPerformance.com.
He can also sell You a smaller pulley if You want to run more boost and correct tune to match it that will not hurt any. He will include all tranny adjustments etc. to go with adding the supercharger. I would recommend a boost guage and air fuel ratio meter or lights. There is a new on dash double pod guage holder, for 2 1/16" size I think meters, that just was introduced at SEMA last week or 2 ago. Looks nice and will keep guages in easy view. The guages are cheap insurance.

If You are into Your own tech world like Me You can get a program for Your laptop from HPTUNERS.com and tune Your ride Yourself. Not hard and the website has a how to quick start section and many people offering support to get You going. It really helps You to understand the complete process of how tuning air fuel along with tranny tuning etc. all work together. Then the nice thing is You can then tune other H2's that are of same year as yours whether they have supercharger or not as HPTUNERS.com are not VIN specific unless they changed very recently. You charge people $200 for a tune that is involved with A/F adjustments or just $75 or $100 just to adjust tranny settings etc. away from engine itself. You can tune the engine without a supercharger just to get them the most out of the engine just like a handheld would do but custom tailored to each rig rather than generic. I have not tried it yet but, I'm almost sure that You could tune any same year model vehicle with the 6.0L engine but, I know last checked You could do other H2's for sure, something to check on. You plug Your laptop into OBD2 port just like a handheld and does a light tune I call it, since You will not be using the I/O enhanced side since You would not be using the wideband area of program to get real indepth tune. But, on laptop You get real time info as the vehicle runs down the road while scanning to build tune if You do not have a dyno.
It is extremely interesting if for no other reason than doing it yourself and knowing more about what is going on with Your rig than anyone does.
So potential to make the money You spend on Your own personal tuning software back that You pay for software. Then work on recouping money for Boost A Pump and then the supercharger. Then all Your Buds will really hate You.

Best wishes on Your new toy. If I can help let me know.

Oh, by the way so all the Buds can hate You more. The price mentioned is
WAY LOWER than at dealer cost for the product for resell. Dragon would be more up to date than I am right now. I know last checked Dragon had Us selling the basic powdercoated kit for $4595.00 or $4695.00 not including shipping and I know We do not get them any where in this universe as low as You got Yours. So kudo's.
