Has anyone done any performance upgrades to an H1 6.5TD. Any good results (PCM, Injectors, etc.)

I've done several(approx.40 or so) trucks with up grade packages in my day, and it is well worth it

Magnum, which mfg did you think gave the best results for the money?

I have used several diff. companys (Heath diesel,SMA,Westers,Predator) and there is only so much gain you can get out of the 6.5, I usually perfer Heath diesel because I personally know Bill and he does his home work.He is a very smart diesel mechanic and has came up with numorus other great products.But everyone is using the same software so it's a matter of trial and error on the dyno.I think retail customers should buy from a recognized name in the industry that deals with large number of HUMMER products like Teaka toys, this way if any problems should arrive they will have much more pull with the manfacture then the here and there retail guy. They buy so much product they can really hurt a manufacture if they feel they a not producing quality stuff, let them fight the fight for you if need be.
