My dyno ate its hard drive a few weeks ago. Today it got fixed and newer software....$890 dollars later. I got a little nostalgic looking at all the old graphs. The old tbi with vortec heads and the ram jet cam did pretty well for a light tow rig, it was the 4l60e with mile wide ratios that finally made me move on. This is a graph comparing the last pull I did of the tbi 350 with a burned chip to first pull of my bone stock untouched tune 1996 l29 454 c2500. L29 is in red. I dont have the 96 l29 anymore either. Still fun to look at comparisons. Comparisons on the same dyno are much more meaningful than having a keyboard warrior punch out that they made 3000 bazillion hp on their tbi. Calibrations are very easy to change and it offsets the curve from there.
