N/A 3500cc Cologne V6

[3.5cologne]

Had my 3.5L Sierra 4x4 Estate on the dyno today.
I built the 2.8/3.5L engine back in 2014 and have slowly been upgrading since then.
The car is street only and will see no competition, so priority was drive-ability with reliability.
This lead me to change from a fast road cam to a mild road cam from CompCams with a advertised power-band of 1200-5200rpm.
It's running EFI with a Speeduino ECU.
It's a dream to drive in traffic and I tend to use 5th gear constantly even in 30mph zones, with no need to change down a gear even up steep hills.
Couldn't be happier with the results

I forgot to add that the other graph on the above dyno sheet was from the last time it was at the dyno back in 2017 to compare. Had back then the K-Jet injection and a fast road cam 181hp@wheels and 193 ft lb@wheels
