5.3 supercharger help

[whylee]

Looking for advice here, I have a Hummer H3 Alpha with a 5.3. I want to add a supercharger but all the kits seem to be discontinued for the H3 Alpha.
On the Hummer forum, I was informed that the Colorado kit will fit as it uses the same platform as the H3. I was also told to get in contact with James from supermod on this forum, as he may have some insight on this subject as far as tuning goes. Any help with locating James or any other helpful info on this would be great. Thanks.

From some minor digging the Hummer 5.3 and Colorado 5.3 both do share the same engine code. While peripherals may change between the two chassis because they are not that same chassis from my reading the core engine should be the same. I mean they are both Gen 4 LS engines, sensors are all in the same place between the two chassis.

As far as tuning and LS is an LS is an LS. Any tuner should be able to throw a baseline at that and tune it. Not really a great mystery.

Thats what I have found, There are minor differences in mounting the cooler pump hoses but that should be minor fix's. Biggest concern is a proper tune. I hope since magnuson used to tune them, that they can still offer that service.
Thanks for the info.
