95 gmtd scantech example

[chrisk1500]

This thread is for people who are wanting to compare their data to the data of a well-running truck.

I took this snapshot on June 7, 2008. Ambient temp was around 18* C.

The truck had just been on a quick highway run. It starts on the first or second crank all the time.

Fuel economy is decent (I would guess high teens). I can get about 550 kms out of a tank cruising at 125 - 130 km/h.

This truck has a Heath HP4 (keep this in mind when reading my timing numbers).

It has a freshly rebuilt IP and HO injectors.

Yes I remember working on TCPL in Moose Jaw area once, guy complained about his dog that ran away from home, & he watched him run for 3 days.

Cool Post. I just got GMTDscan. Now I know what to look for.
