Twin Turbo 4BT Dakota on the Dyno

After a few years of dissapointment with this truck, I've finally got it to stay together long enough to do a little bit of tuning on it. Here is a video of the best pull I made with just a little bit of AFC movement.

I also attached the dyno sheet from my break in runs.

Oh I see, how do you find the sweet spot with it? I see you made the most power at 3800 even tho the engine revs higher.

I think it would have made power higher but it hit so hard that I got scared and ended the run early lol.

That is awesome! Congrats man. 553 hp is pretty impressive out of a 4bt.

I've always wanted to build something like this!
