Cool DP Tuner Chip Review

Guys,

I've been running a DP Tuner chip for about a week now and I wanted to report on how it's performing. I had been running an old Western Diesel chip from about 2002 so the programming technology was somewhat out of date. The chip dynoed pretty strong but I was having trouble with drivability and too much ignition advance hampering on road performance.

I went with DP's 6 position chip. The chip comes standard with 1 program. The selector switch and additional programs are sold separately. I went with 3 of the 6 possible programs including: 40HP Tow, 80HP Econo and 120 Race.

Just some general observations:

The engine sounds distinctly different. Much like an older Powerstroke with single shots. It has more of a "growl" to it at all RPM ranges.

Throttle response is much improved. The engine revs quicker making double clutching and shifting more coordinated. The power comes on sooner, with much less application of throttle.

With the old chip, I could not mat the throttle without the engine going into severe detonation. I could literally feel the engine loose power at full throttle then pick up again when I lifted. With the DP Tuner chip, I have full use of the entire throttle range.

The truck pulls like a freight train throughout a wider RPM range. Before, with the old chip, it had a much narrower power band.

On the 80 and 40 HP modes smoke has been greatly reduced when the engine is lugged. The turbo also spools up much quicker.

On the dyno:



I made 3 runs on the dyno. The first with the old chip and 2 more with the new chip in the 80 and 120 mode. The first pull with the WD chip yielded no suprises. I had run this chip before and the numbers fell within 5 HP and 10# torque of my previous numbers.

The second, on the 80HP mode yielded a nearly parallel line with a small decrease in peak HP and a more significant drop in Tq. The overall pattern, however, is much flatter with more space under the curve.

The third run on 120 HP mode was again nearly parallel to the original run but again, the power was extended significantly into the higher RPM ranges. This has proven out on the road as well as the truck pulls much better into the upper RPM's.

Overall, I netted about 12 HP vs. the old chip but the improvement in drivability far outshines any numbers on the dyno. I feel as well, that the injectors and boost have simply met the end of their capability and the HPOP may be giving up quite a bit as well.

Thanks go to Jody and Diane at DP Tuner. Great folks to deal with and very pleasant in person! :Thumbup: :thanks:

Thanks also to the guys at Ed's Diesel Performance for bringing the dyno out to Mooresville and letting me take the time to do a little chip swapping while strapped on. :Thumbup: :thanks:

I hope to see you all again sometime! :bow:

It sounds like we missed a great show :Thumbup:

Those numbers are right up there for your truck on a no load dyno. Keep working on your little projects and you will see more. :HappyMugs
