As promised here it is. Still have a lot of work to do in the tuning dept. though. it still trys to add/pull fuel at the same time between shifts as I didint know what I was doing in the engine torque file at the time. It also needs less timing down low to help light the charger, and by the looks of it I have room for more fuel.

In addition to finishing up a few things on my truck today, I also plug the resonator on 4 of my buddies Dmaxes, rerouted the PCV on two, installed a boost valve in one and did two exhausts. It was kind of our own little Dmax party.

^^^definately . It is not very fun to drive right now. Especially with the amount of timing down low. If it stays in gear and is under 1800RPm the turbo never lights. I have a lot of tuning to do with it.

And of course more fuel.

Those tires have 5,000 miles on them and they are about half tread. Ill rotate them at work tomorrow and listen to all of the crap I get. Theyre cheap little guys so It dont bug me much.

well guys I spent a lot of time on the phone with guy today and got my Firmware updated. Thanks a million for doingf that guy, you gave up an hours worth of time to help me. And I couldnt of done it without you especially since my V2 was acting up and I didnt even have the right firmware file on my computer.

After rotating my tires again, changing my oil and removing the indoor stack to replace with the regular stack, i spent some time tuning and got a good start. I Retarded the timing down low some and was able to light the turbo a little quicker. I tried new things in the torque tables and it shifts much nicer now. I also slowly kept adding more fuel until rail pressure started to suffer and within 3 different tunes and about 20 minutes I was able to add enough fuel to gain 7psi bringing my boost to 47psi. It was dark out so i couldnt use smoke as a tuning aid but I will be tomorrow. Im in a very good modd right now since I can finally tune my truck again. I also got rid of the 18,100psi rail pressure at idle, still not sure what caused it but after a few tunes I was able to get it to tame back down to 5,000. I know there is still a lot of potential left but I was pretty satisfied with what I had accomplished tonite in short time. Its a lot quicker than it was this weekend, and even more fun to drive.

more later.
