Tuning under the curve is EXTREMELY important for an engine that will see time other than full throttle. Case in point, I had an old 1991 Chevy Cavalier station wagon with a mild turbocharged 3.1L V6, and a Haltec standalone ECU. It was tuned by a VERY popular import tuner in north Dallas. The car was getting 16 mpg!! I found that timing was locked in at 10 degrees and the air/fuel ratio hovered at around 12.0:1!!! WAY too rich and not enough timing. After I tuned the car, gas mileage went up to 25 mpg, the car gained hp and torque on the dyno, it was a LOT easier to start when it was cold, and it didn’t pop and buck at low rpm’s. Tuning under the curve is VERY important!

Nice! A longer video with engine specs, jetting and tuning breakdown would be excellent!

This is EFI, so there aren't any jets. I also don't know what is in this engine, just what I have added on top :)

What sort of Dyno is given you instantaneous torque values, a water brake?

[@thedubshop]

Yes, I use a Land and Sea water brake :)
