Is this a good combo the MP 1.7 RR's with the hypertech power programmer, or should I step up to the MP computer.

I wouldn't hesitate to use that combo. I'm actually giving it serious thought at the moment. I think a set of Crane's new rockers would really be a big imnprovement.
The problem with the MP computer is that you can't change anything. If you're having fun with your truck, it's a great item. But what happens when you want to do some work? Like tow a medium to heavy trailer? Or you get a tank full of crappy gas? With the hypertech, you can spend 5 minutes and change the settings to something more trailer friendly. It almost takes longer for me to find the tuner in the basement and plug it in than it does to actually change the programming.

The mopar computer might not be programmable, but it is soo much better than the hypertech. It will actually raise shift points, give you a true 6000rpm rev-limiter, and completely eliminates the speed limiter. It does other cool stuff as well, like shut off a/c under wide open throttle. The hypertech only lets top speed and rev limiter be adjusted slightly.

Riv, the 1.7's are going to give you a honest 12-15HP increase over your stock rockers. The Mopar has dynoed alone with about 22HP over stock.

With both, maybe 30 to 35 or stock?
Not sure if it's worth the cost, has any priced this kind of combo?

With both you'll most likely see 25-30HP at the rear wheels over stock. It is worth the cost as your truck will behave differently. As with adding any mods, you have to try the tried and trued of fellow dakotas already. They are as follows......1)K&N air intake..or something similiar, 2)M-1 2bbl Intake, 3)Mopar PPH or GS Motorsport headers depending on your budget, 4)Computer Flash...ie BG Flash, Mopar..these 2 are far better than the others, 5)1.7's, 6)52MM Throttle Body. Any of these mods, you will feel and see a difference in power and performance. Good luck.

I already have the PPH headers and M1 intake(still in the box).On the truck I've already got an open element air filter, milled , ported and polished factory throttle body, accell 300+ ignition system msd 8.5 wires, splitfire plugs(colder than stock)180 thermostat,and a hypertech programmer. With this combo it ran 15.0s same as stock. As soon as my back heals on with the intake and exhaust, by this time I should have enough saved for the rockers, and valve covers as well. Hopefully it'll at least break into the 14.s

Also I was wondering if a 160 thermostat would be any better than my 180??

many people & websites have confirmed that the 160 tstat is too cold, & makes your truck run like crap since it can't get up to operating temperature.

That's correct. The 160 trips a code in the PCM for running too cold for too long. It doesn't turn on the check engine light though, so many people never know that it's a problem.

You won't need valvecovers if you buy the harland sharp 1.7 rockers they fit with the stock covers,when you finish installing every thing you have to GET the B&G flash you'll be much happier with the results ,I've tried the mopar pmc and didn't like it compared to the B&G

Get rid of the hypertech and get the BG Flash. On my 5.9, it added 30HP to the rear tires. I know for a fact that hypertech doesn't even come close to that.

Southeastrt.com has the HS 1.7's for $299 plus $12 shipping. Just email John I believe his name is. The 1.7's alone will give you 15-20HP and 15-20 ft lbs of torque over what you have now.

On a stock cam your lift increases with 1.7's from .410 to .440 lift. Piston to valve clearance is no worry until you get to something like .462 area. I just put Harland Sharp 1.7's on my stock motor. It definitely is more torquery than ever. It added about 15-20hp over the stock rockers.

I read this article from Mopar Muscle Magazine http://moparmusclemagazine.com/howto/38620/ about the conversion to 1.7 rockers. Very interesting. HP numbers mentioned here are considerably higher than those obtained on the dyno. For example, spali claims 20hp: dyno tested? any other mods?
According to their test (FWTW), max hp gain was about 9, at 3,400rpm. at 2,400 rpm's, the gain was only 3.7hp; certainly not enough to notice. At 5,200 rpm's, the gain was only 6hp. At best, it's almost $35 per hp.
If you're racing, this is well worth it for the additonal durability and valve train stability. Especially if you add Comp Cams new beehive valve springs. For the average street driver/tow vehicle, I'm not sure it's worth it. I've been considering this for a while. Maybe it is, but based on these hp numbers I'm not convinced.

If you'll check the article again you'll see those are Crane's dyno spec for a V-6 Magnum.
You'll need to add approx. 33% of those #s for a V-8. That would put it at a 12hp gain over the V-6's 9hp. Close enough to Spali's claim of 15-20hp that I wouldn't call him on it.
Plus, I doubt they ran the combo long enough for the PCM to reach it's learning curve. Where as the numbers they used for the stock comparison *might* not have been with a "cleared PCM" before the test run.
I installed my Harland Sharp's only about 150 miles ago. After the install I took it out for a spin and could feel the difference immediately.
However there was a learning curve for the PCM.
The most noticable was when I would run the engine up to say 3500rpm (or any other speed)and let off the gas, it would hold there for a moment before going into compression braking, kind of like if you were holding the gas pedal down to maintain your speed before it would let off. That lasted for about maybe 50-60 miles.
It runs better now than that first drive after the install.
Most of the guys that have done the install say to give it 500 miles. If it doesn't get any better than it's doing right now, I'll still be very happy with the improvement. You can definitely feel the difference all across the rpm range.

.boB, I bought my Harland Sharps from Southeastrt.com for $311 shipped. I have sat back and watched other R/T's dyno over the years a good 15-20HP when they switched to 1.7's. You can definitely feel a difference with them on. But as Idano has said, the PCM has to learn and adjust to the new increase of air coming and going out of the engine. Now that I've driven 200 miles on them, the truck even feels stronger. This mod does work, no doubt about it. If you do some research on what other 5.9's are adding as far as mods........most everyone swears by them. Another mod that works is the 52mm TB(I chose a Fastman). Once I put that on for the 1st time........a 40mph roll in drive when punched downshifted to 2nd gear and chirped the tire. My truck never ever did anything like it. It goes to show the extra incoming air will make the engine breathe and perform. Last week I went to the track for the 1st time. With slicks, I ran 14.711 @ 94.40mph with a .113 reaction time. The truck weighs 4500lbs with me in it and I just happened to have 3/4 tank of gas,(8lbs times say 18 gallons=144 extra lbs, 86 degree weather and my 1st-2nd shift does not shift under full throttle due to my stock VB needs a performance upgrade. So I was coming off the line and letting off the gas completely at 5300rpms and then hammering back into the gas in order for it to shift to 2nd gear.
