Guys, that video posted was a different truck, with a Whipple 2.9 and not using a dedicated drive. I do have videos of the dedicated drive 2.3 Whipple while I was tuning before I was finished, but I was tuning in a 3/4 shift flare so I didn't post the video, I stopped recording after a while and just focused on fixing the flare so I don't have a finish tuned video but it was pretty close to being just as fast as the truck with the 2.9 whipple.

I did open the exhaust cutout and it did not gain any power, however, if I retuned it with the cutout open I know I could have gained a good bit of power, but I did not bother spending time doing that at this point because I never open the cutout. This may change with the next round when the boost goes up, I will spend time tuning WOT with the cutout open and if the gains are drastic I will just use WOT with the cutout open and it will be tuned accordingly.

So, an update on this project. We took out the fuel sending unit last week and shipped it to aeromotive for them to design an in tank bolt in pump and sending unit, once this is done we will design the rest of the fuel system around it.
