Im a new visitor here but from what i have read over the past few days i am very impressed at the info that you all provide. So with that said clue me in here, i havent been able to find much info on pcm's and tuners, and whats the flash that i hear about? Do the hypertechs have the same programs that they upload in as the mopar pcms? Whos gains are the best? and how much will the mopar pcm hurt the emissions, i live in a emissions testing state, so would it be better to stay with the hand held? And in the winters here in CO the put so crappy addatives in the gas will that be a bad thing come winter time? Thanks so much!!!

All the tuners, chips and computers do basically the same thing - change the fuel and timing curves for more power. In live in Colorado Springs, and drive an '01 QC 5.9 4x4.
A while back I used the Hypertech box. It's a little cheaper than a new Dodge computer. I think one of the big advantages is that it's quickly reversable.
The programming made a huge differance in drivability and performance, and a small improvement in fuel mileage. Well worth every penny.

FYI: If you drive a 4.7L, you are out of luck for a hypertech/superchips programmer. The aftermarket jumped straight from the 5.9 R/T to DC's baby, the HEMI, and skipped right over the 4.7L.
If you have the 4.7, the only way to get a change of performance from altering the computer is by wasting your money on a Jet chip, sending your PCM to FASTMAN or Kenne Bell to get flashed, or buy a MOPAR performance PCM. You can trick the PCM by moving sensors, changing Cams, enlargening your Throttle Body, or resetting it for 200 miles.
I see two corrections to the problem of poor aftermarket support:
1. Wait until the HEMI hype wears off and pray that DC keeps putting the 4.7L in their vehicles.
2. Swap your engine out for a HEMI.
Good luck either way.

Opie - while there is a part # listed, I don't believe the Mopar performance PCM was ever released for the 4.7. For anyone with a '00 4.7, the Leach Flash (lots of info on this site if you do a search) is also available.

But what Ive read Leach wont touch '01's or above, right? Do you know what the best option for POWER and money? I have a '01 4.7 that im looking to build up - So far the intake and exhaust are done. I was looking to do some come of PCM flash but with all the jarber out there its hard to tell what works the best for these 4.7's. Any input?

I also live in Colorado Springs, Hi Bob. I have the KenneBell Optimizer II PCM upgrade on mine, and have been thrilled with it since I got it in Germany. I just sent a freind of mines in and had it done for him, and he is thrilled to death with it.
Like tanked said, I don't think Leach does anything newer than 2000, but check with them and see. They do not make a PPIII for the 4.7L, but i read some disturbing news on this site the other day that said 'the PowerProgrammer III does nothing for a modified engine'. Look it up. And MOPAR has a part number for the PCM, but never released it.

Yes, as far as I know Leach is still for '00 only. For you guys with the newer models, Old Fool gives good advice - lots of people slam the chips but I've only heard good things about the KenneBell. I got around the downtime by picking up a used PCM at carparts.com for $80 - worked well for me, but some have reported trouble running different PCM's - I believe it has to do with whether the doner PCM or your truck have factory alarm, one combination they say doesn't work. Someone had it figured out a while back if you need to search that. No alarm for either with me and no problem with operation or lights. If I wrecked my truck tomorrow I'd order the same one (o.k., with 3.92 gears) and be on the phone for a flash - felt like as much more power as the HO cams.

Sorry its on a 98 5.2 4x4 i have: intake, gibson single in/ single out, soon to have a electric fan and t-body. i guess for emissions here the hypertech would be the way to go im just not sure if its as good as the rest? Thanks for your input! and by the way since i live at about 5000ft would the 52mm t-body be better than the 50? will i loose a lot of low end with either, and is it worth the money? if so who do i buy from fastman, aps, or f&b? thanks again guys!!

Since you have the 5.2L I would get the MOPAR PCM available from MOPAR. It can be changed back to the stock PCM in about 1.5 minutes when you get ready to go for testing, if you feel it needs to be stock. You can purchase these at your local Dodge Dealer.
As for the 50 to 52mm Throttlebody which one to get comes down to Personal finance and what all you are looking for. If you loose any down low torque it isn't enough to be noticed by a seat-of-the-pants dyno.
I don't know about APS, but the Fastman is a stock throttlebody that has been bored out to 52mm. It works OK from what I have seen and read. It is a bit less expensive than F&B. You get some of your money back when you return your core (old throttlebody).
The F&B is asthetically superior to the Fastman since it is made from billet aluminum, but since it is a billet piece it will cost a bit more money. The other side of this is that you get to keep your stock throttlebody. Also in the dyno tests that F&B has on their site the F&B performs slightly better than the Fastman.
Sam has the 52mm t-bodies for $465 shipped.
and The Fastman has them for $330, you keep your core, or $250 you send it back.
