I was looking at PPE's site and they show programers adding 425hp has anyone tested these? If so what were the result and what other mods were done with the programming?
Also camcojb they say that every 10lbs is 1hp so in a car weighing 300lbs less than a truck that 3000 lbs would be like adding 300hp. I am sure that is just an estimate but I would think that 3000lb difference would at least put the car in low 11s if the truck is in the 11s at all, possible high 10s. All while getting 23+++ mpg.

I would do the head studs since it's so easy with the engine out. I also would go with EFI Live instead of a PPE tune. Nothing against Dan at PPE, great guy and very good tuner. But his performance tunes are as much or more than EFI Live, and with his you can't do the tuning changes. With EFI Live you can change anything in the tune so if you want to try more boost, change the fuel, timing, etc. you have immediate access.
The biggest problem you'll have is traction. The street trucks that are the quickest are almost always 4wd, and there's a good reason for that. Even though the 4X weighs more and has more power loss down the track due to two diffs instead of one, they launch much harder and traction is way better. The 2wd trucks are rarely as quick as the 4X's, unless it's a drag specific truck, because they cannot hook 1100+ rwtq. You're gonna need slicks for sure for any track duty, and it'll still be a learning curve to get the car to leave decently. If you get it to hook well, you'll easily run 10's I would think, but not sure how easy that will be to do. Mileage, can't see any way you can't get well into the 20's on the freeway.
