JET or PCM for less???? Need direction.

[HoosierH3]

The JET website is not up to date. It only reflects a spacer for H3.

I spoke with JET customer service today after talking with one of JET's distributers. The distributer is selling the same part number as they sell for the I5 3.5 Colorado/Canyon per JET's instruction. Same exact part number (JET20305) stage 1.

Per JET customer service..they are using the same exact part number for Hummer H3 as earlier Colorado. I confirmed this today with JET. According to JET tech service, "the H3 factory programming is nearly identical to 3.5 Colorados. Part number 20305 works on both with the same results." Wether this is true or false, I do not know, but this is JET's claim.

After reading many threads here pertaining to PCM for less, it does sound that both vehicle are set up similar from the factory, but not identical. Close enough though, that JET's module works in both vehicles.

JET tech service did tell me though that their module only adjusts for fuel/air ratio and timing. No mention or consideration for shift patterns, rough idle, or odometer recalibration obviously.
