Change the lower pulley.
Plugs, if you're running HT0s (should be in there) you need to gap them down to 35-38. Normally they are set to 42. They aren't supposed to be able to be gapped, but there's a trick to get it done (let me know if you need to know the procedure). If you're runnng Brisk plugs you'll need to gap them down as well, they can be gapped as they use a standard plug end.
Injectors are okay.
The MAF... the Saleen damn near maxes out the MAF with normal boost and tune, and there are reports from tuners that it will completely max out with more boost. I recommend you get SCT's MAF for the truck.
Who's going to be tuning it?

+1, my truck was dyno tuned by a mustang shop one summer. Once I got to the cooler fall and winter temperatures, it started pinging (detonation). I took it back and the tuner changed the tune 4 times and couldn't get it to stop. He then claimed something was wrong with my truck. I then got tunes from Troyer Performance and the pinging went away. Be careful with these shops.

How does the price compare for the work to be done. Thanks also for the words of wisdom. TOO much money invested to be putting another mtr. in.

Mike Troyer often does a better job mail order with supercharged trucks than many shops do with your truck on the dyno because he specializes in F150 and has done a ton of Roushcharger, Lightning, Saleen trucks, etc. Check them out at TroyerPerformance.com and call them. If you let them know you're from Ford-trucks.com (they'll ask for your user id) they usually give a good discount. Don't expect to get your tunes in a week, Mike is in high demand.

3.2 for +2 lbs. and 3.0 for +4lbs.
You need a bigger MAF housing and a custom tune before adding any boost. The stock MAF is already maxed out at stock boost, so if you add boost you will vent your block.
My suggestion would be to order the kit from JDM or Troyer.

Thanks for the response. I'LL take your advice. The thing is running better with more miles on it. Sure needs a pulley and tune to get that real get up an go that they lack. One fine truck. Love the ride and drive. Thanks again.

Pegging out MAF
I know this has been posted a while back but with new information available I though it was a good idea to provide what I haev learned. Since buying my S331 in January I have had EXTENSIVELY long conversations with MIke Troyer about boost upgrades for my truck and here is what i finally decided to go with. I got the stage 1 kit from mike which includes the Boost pulley, Sct programmer, and cold air kit. He says with their experience of this kit on the saleens the dyno has repeatedly shown an increase in horsepower in the 100 range. And the point to my post is the kit DOESNT include a new MAF because according to MIke, it is NOT pegged out stock nor will it be with this kit upgrade. Just FYI for those who have heard or been led to believe that it is. I feel pretty sure that MIke is a reputable source and trust with his experience with this truck and motor that he knows what he is talking about.

yes
Will wake the sleeping beauty up. Not sure about the HP gain. Depends on other things as well. 400 hp @ the rw and 450 torque after install. You'll need some cheese for the whine. The S/C WILL TELL YOU IT IS THERE FOR SURE.

I have an 07 HD Saleen Truck. Mike Troyer did a SCT tune set for me via mailorder. Truck runs great and I could not be happier with Troyer service. I did not go with a larger pully just yet. Truck only has 6K miles on it and I don't want to mess with the warranty yet. About the MAF on the Saleen set up. I am pretty sure Mike did tell me that I would need a larger airbox with the pulley upgrade as the MAF is very close to maxing out. Perhaps Mike can comment directly and calrify if I have some facts incorect here.

Also... those of you that keep saying just change the lower pulley and not the s/c pulley. It's not that simple. The Saleen blower runs on one belt. The same belt that drives your AC, power steering, alternator, etc... It's not like the Roush or the Whipple that have a seperate s/c belt. If you change your lower pulley with the Saleen blower you with alter the operating speeds of all your belt driven accessories.
