Ok guys, I had my 4.10 Precision Gears installed, and now I need to know what I am supposed to do! :D

 

Do I need to take it to the dealer and have it reprogrammed to the 4.10s from the 3.73s?  If so, how much is that?  Would it be cheaper in the long run to go with the HPP3 Programmer?

 

OR, can I do nothing, everything is ok, etc...  It seems to be revving high on the RPMs while on the highway, and the speedo seems to be off.  

 

Just lookin for advice, thanks for your help!  

 

:)

The dealer would charge probably 100 bucks I'm guessing.  IMO spend the 320 now and get the HPP III, not only will you be able to adjust for the new gears but you'll get some more power to boot.  That would be the easiest route to go.

How easy is the HPP3 to use?  I don't want to screw my computer up?!?!?!   :D

 

But, more power and the new gears, etc...   :)

 

Thanks.  Where is the cheapest place to get one?

It's really simple to use.

 

Once plugged into your OBD II port,the unit prompts you for changes by asking you a series of yes/no questions.

 

What you want your truck to do is entirely up to you from there.

 

For te best price,you'll just need to check around.Maybe you can find someone running a sale on them but,IMO,if you find someone trying to sell a used PP#,don't do it.Save yourself the possible headache of any problems with it working on your truck and buy it new.

With 4.10's I turn 2400 rpm at 70 mph.  It should be about the same in your truck... (just for your reference... until you get things recalibrated)

 

OOPS...  that's 245/75 tires and not bigger tires like you...  I'm guessing you need to turn about 2 grand on the tach at 70 mph

Thanks for the replies guys.  I think I will buy a new HPP3, and go that route.  I have seen people trying to sell them used, and heard all the woes of compatibility issues.

 

My truck rocks!  :)   Sorry, I get carried away sometimes...

Hey, talk to RyanBab, there's a plac in Indiana that sells them for 270 or 290 I think he said,  either way it's still cheap.  He's go the number for them.  That's where I'm going to order mine from, you can't beat the price.

Did you call them yet?  Just wondering what they said.

 

I paid $279 for mine plus tax.  Cheapest anywhere.

 

let me know if you want their info

I'll probably get it after I come back for Vegas.  I'm a bit strapped for cash since I just forked over about 400 for the carpet and console.  So, hopefully next month I'll drop a paycheck on it.

      OCI, not when but why?

      By Chuck FB · Posted

      I had skimmed through that article when you posted the link and honestly I felt rather defeated in a sense and realized that all these years in changing oil that in fact putting in what I was told was a good quality oil was probably not filtered as well as it should be although the filter put on the engine would be what ( as long as it never went into bypass mode ) would be the final filtering of the new oil that the engine components would first see, but then the filtering media itself is not up to par to what is ideal because a full flow filter would be too restrictive to filter fine enough for the engines best outcome in the long run. Only one of our tractors over the years which was a Versatile with a 855 Cummins had a separate bypass filter, some engine manufacturers did spec a partial bypass system within the main oil filter but I don't believe any other trucks or equipment I was servicing used such a filter. No doubt a product like the Amsoil bypass system is of benefit as long as nothing goes sideways with the extra plumbing and filter such as a rupture/leak that could cause the oil to pump out of the engine ( yes that Versatile had a remote canister with hoses routed to it as well ). With the idiot egr system on a diesel and as a result forcing a lot more soot into the oil, that certainly isn't helping the diesel engines cause or as you pointed out the GDI engine issue with creating more soot and aside from having a fancy secondary filtering system, changing the oil more often helping lower the total soot load.     So oil manufacturing and the end product is not something one can control and I wonder if there are specs on what various oil packaging companies produce in particle count or size. As to the filtering, if the OEM is not designing a filter size and spec that is really what it could be, they too are short changing the end user and so what is the answer. Of course as you say the oil side can only do so much if the air side isn't keeping up its end of the picture and air filters are only so efficient and if in a dusty environment such as farm or construction or driving gravel roads there is a lot of dirt to filter out and some of that ends up into the air stream.    Of course the irony in places like where I am where they dump the salt on the highways but also will mix in some calcium or outright pure calcium for problem road area's, or using calcium as dust control on gravel roads, the vehicle that gets used in that environment may rust out before a properly engineered engine and maintenance finally wears out so one has to face that reality in the rust belt.

      Oil Change

      By Erfar · Posted

      have you stuck with dealer oil changes since then? I made the same switch after getting tired of crawling around under the truck, but I’ve found some dealers are way better than others about getting you in quickly. Curious if yours has been good about scheduling or if you’ve had to look elsewhere for quicker turnaround.

      Can anyone decode a VIN to determine if this truck has had emissions issues or a recall?

      By cherryred21duramax · Posted

      Thank you.   I am set on a 3.0 Duramax as my previous truck with a Ford Ecoboost had just as many, if not more, "common" issues.  Cam phasers, timing chain issues, 10-speed valve body and CDF drum, emissions issues, etc.  So I figured, why not get 2x the fuel mileage (these things got 27+mpg on every mixed city/highway test drive I put them through) and better towing capability with resale value to boot?   My minimum, shortest trip will be 50 miles 1-way and I regularly go out of state with a travel trailer.  I'm planning on using this for a marketing/event promotion business also, which would require regular towing of trailers for bands, DJs, sound and lighting gear, along with my personal camera gear for filming events.   Looked at other trucks in the $30k+ price range but the issues seem to be everywhere, plus too many with gaudy mods.  I'm literally sticking with RWD trucks because they tend to be actually used as trucks, vs. the 4x4 models I've seen with unsafe lifts, huge tires, and general mods that would affect reliability (I'm wondering if some of them were tuned, hence the aggressive throttle response and hard shifting).   So my goal is to find a stock, 3.0 with 1 or 2 owners, in good physical condition, and decently well maintained.  Can't seem to find that up here, everything in the $27-30k range has had multiple owners, smoke smell, issues, or body damage.  Or the ridiculously modified trucks with 80k miles for under $27k but lots of problems...

      That’s pretty tough Grumpy. I reread the previous few posts. They all reference oil changes. Much like your last thread. In my humble opinion it keeps things interesting.
