Piggy-Back units do not replace the original ECU, instead they piggy-back onto an existing system and intercept / change the signals from the engine before they get to the ECU.
PIGGY BACK units also do ignition mapping, extra injector activation, launch control, open and closed loop lambda, logging and real time tuning WHILE YOU DRIVE, all with the original ECU still present!
Basically they allow you to use a laptop to tune your a/f and timing for better performance.

There are guys runing a two stage 100 then 150 with no problems. Then there are some runing a 75 shot and blowing up their plastic intake.
Dropping two seconds with just heads and cam will not be easy. What heads are you planning on using, p&p 5.7 heads? 6.1 heads?
What about a CAI and cut-out too to help that Hemi breath and exhale.

Yes, 13's for sure! You don't need the gears since your are using nitrous. People who have switched from 3.92 to 4.56 have not gained in the 1/4 only the 1/8 plus if you are fast enough you will run out of gear at the end of the 1/4. You want to finish the 1/4 at the top of 3rd gear and not in 4th.
I have 4.56's but I needed them to help spool the turbo at take off. Now I have a high stall tc so spooling up quickly is no prob.

I have an STS turbo doing 413rwhp at 7lbs. That was a 2nd gear pull on 23" wheels. Soon I will be doing 16-18lbs on a built block.
Even with the 4.10's you should not hit 4th in the 1/4 unless you are in the low 12's. The Superchips will actually help because you can increase the shift/rev points so it doesn't go into 4th until 6200 rpm's. You want to cross the trap at about 6K in third for best times.

I run it at 3.5 psi on the street unless someone pulls up next to me then I hit the switch on the boost controller and go to 7lbs. The truck weighs 2200lbs with the 23" wheels, 12" subs and amps, tonneau cover, 20" steel spare, tow package etc. I ran it once at the track in low boost because I was runing lean and only got 14.5 at 98.xxmph. That was in street trim with nothing removed. I one raced a friend in another ram with a turbo who does 13.1 and was door to door with him at 7lbs. I have beaten plenty of SRT4's and cars runing 12's on the freeway but from a take off I am not as fast because of the weight. Also, that was my first and only time at the track and it was freeking hot and humid at the CA Speedway. If I had spooled up the turbo off the line by brake stalling and full boost I would have done a lot better. I now have Nitto NT555R's with 17" wheels for the track, 4.56's, high stall tc and a good tune so we will see.

I think it is worth it but that is just my opinion. If a truck is running low 14's before the tuebo it could be in the 12's after since you can see about a 1.5 sec drop but if you are in the high 15's you may only be able to see high 13's or mid 14's. Tuning was an issue originally but we figuered it out and are runing strong right now. I replaced the 8 stock injectors with larger units and removed the aux(9th) injector. I have a piggyback controller that I use to dial in my a/f, timing and meth injection. You can see a pic of the truck at www.ElColasMotorSports.com
I also have a nitrous setup installed but have never used it. I wanted to use a small(40) shot just to get out of the hole and help cool the intake charge but decided to build up the engine first. http://i47.photobucket.com/albums/f1...R/Nitrous4.jpg
