I would say that's a big 10-4 on the live tuning.

 

OK, I forgot to ask about this as well.

no matter which chip I purchase, Ill potentially be getting close to boosting more then the 25-27psi and throw a code for overboost (my truck on stock tune runs 20psi steady) Which overboost preventer do you guys use and reccomend.
My experiance is with the boost anniahlator, which basically is just a regulator set to not let the map sensor read above 23-25psi or something im guessing. My brother has it on his truck running the dp tuner and seems to work nice, but its kinda bulky and personally I like electronic mods. http://www.itpdiesel.com/store.php/products/Overboost

What about the map-maximizer. http://www.puredieselpower.com/catal...sels-p-91.html
Who is running the maximizer and how does it work.

What is preferred when runnign more then 25psi boost.
By the way, Im leaning to the DP tuner, Ill make up my mind tomorrow before noon probly, that way i can get it ordered and have it here by middle of next week.

forgot to add, Ill most likely get the 120race with no codes, and maybe the 80econ no codes as well, so will I even need the "boost fooler" and is this even a good idea to get the no codes version.

Thanks again guys, You have been a great help

 

I tow a lot in the summer during vacation from IN to OR or AZ and back. Can/Would you elaborate on that? I'd be interested for sure...

On edit: Would those tunes save me from spending the extra money on coast clutches during a towing trans upgrade?

 

Jody offers "code tunes" which removes the CEL. So no need for any overboost device.

 

I loved that unique option also. DP is definitely ahead of the curve on their controller.

 

I have the ITP OBA. It's not "bulky". Here's what mine looks like (on the extreme left side of the pic):


IMHO, if you tow a lot, you need to mod your trans. The TransGo Tugger is *for* towing situations. It does more than can be done just in tuning, and when you get the tunes to match, it's like a whole new truck all over again.

 

You got me before I edited my post.
What do people reccomend, the no codes, or the "boost fooler"
Does the map sensor do anythign with the fueling of the engine, like when you fool the ecu with the regulator to show only 25psi (as example) and I just happen to be running 30psi (id live that) does the ecu use the map sensor to fuel the engine correctly like a speed density gas engine, or is the map sensor just used for more or less a safety device.

 

Once you get up that high in boost, it doesn't matter. There are guys running 40, 50, or even 60+ psi. The PCM still thinks it's only at 22ish.

 

I only use my truck mostly to tow, and daily drive. I haul platform lifts and 9k forklifts, skidsteers and whatever else will fit on my 12k trailer. My truck has the sonnex valve and tricuumulator springs new internal filter and external filter deep pan and a second trans cooler ready to be installed, just need to ge the pail of schaefers delivered before the flush and relube. I also was tempted to get the trans rebuilt before the fluid replacement, but its "only" got 220k on it, and has a few more miles before its used up.

My brothers truck has the OBA as well, works fine, his is above the map sensor, fits decent I suppose.

 

I have a diy oba on my truck. I mounted it above the map sensor, just like Joe's. I really don't know of any pros or cons with either one. It's more or less personal preference.

 

On Tony's (TDP) Tow programs (heavy tow & light tow) I have the automatic downshift from OD to 3rd at 40 mph, the TC stays locked untill 30 mph - definitely helps slow the load down on the off ramps and steep declines - especially since the EBPV is outa there. Tony also set the shift to OD at 50 mph - keeps me from having press/use the OD on/off button to keep the rpm's up when accelerating while towing. Love the EGT's on the new tow programs (last year) when I pulled the 5th wheel'er to Gatlinburg & the Black Hills, seen similar EGT results from Kwickordead running Bill's (PowerHungryPerformance) tow tunes.

Your gonna need the boost fooler or else the PCM will defuel to bring the boost down.

 

Like Joe, I have the ITP OBA - been on there for 4 years now.

Although I can't tell you exactly what Jody does in the tuning. He has explained to me in depth that he is saving the expensive internals from getting toasted. I have used this many times even empty on long downhill stretches to help me slow down in heavy traffic. I use it often and my tranny is just fine. We have never been called in the 2 years Jody has had this tune (we had customers testing it for several months before we made it part of our tunes list) that a tranny has been injured. There been only 1 complaint. One of customers said it didn't work. He later found out his EBV wasn't closing properly.

Jody would never sway someone from doing an trans upgrade if it is necessary. You can't tell what condition the coast clutches are in without breaking the trans open. If it is being torn apart for other reasons you might as well go ahead and do the coast clutches if they are worn. If your asking if it is a "bandaid" to an already worn out coast clutch issue then the answer is no. If the coast clutches are already in need of replacing theres no reversal. Just get them replaced.

 

Do the "code tunes" actually negate the necessity of a Overboost Annihilator? Or do the code tunes just keep the CEL light from coming on?

 

I had the thought that you gave me 2 60HP tow tunes instead of the 40 and 60. The EGT never dropped during towing even when I went to the 40 Tow. Checked and double checked for a boost leak and was about to call you to check it. The Up Pipe on the driver side was sooty and so was the trans on that side. Any chance DP-Tuner will warranty the leak and get me a set of Up-Pipes?
