I read this thread, among many others this week:

I called them yesterday and was quoted $890 for the new duration and the pressure box. They also told me they would upgrade when the new timing came out. I asked about group buys, but was told that they were not interested.
As of this morning, I plan on purchasing both boxes, ATS manifold, and an AFE Pro 7 from them. I am going to add all that plus a 4" exhaust, with a Donaldson or Walker, I am getting locally and see how the boost and EGT's react on various levels.
I am very interested in a turbo upgrade but I cannot find any out there right now that give me a warm fuzzy. I am going to wait and see how the boost and EGT numbers run, if they are decent I am going to wait and see if any turbo's come along later this year, if the numbers are bad I will most likely go for a B1 or a DD Jammer.
I am also watching Vaughn MacKenzie's progress with the modified valve cover here:

Once Vaughn posts about how he solves the breather issue, then I want one of those too!
I thought I wanted a TST. The more I read here and the more dynos I saw I started to lean away though. From what I have read and been able to research the TST just comes on so hard down low that it scares me. I had a VA on my 2001 and it was so sweet I just forgot it was there and this new one seems to be a milder version of the TST. I am wanting to land somewhere between 400 and 450 HP, with the least amount of rail pressure as possible.
I am rambling now sorry... this is what happens when your truck is in the shop!
It sure seems like there are allot of people around that are interested in the VA's. I sure do not mind waiting a week or 2, if someone gets a large purchase thingy going. My truck is having the windshield, roof and hood replaced from hail damage so I have a bit of time before I start all this work.
