the tuner i had was a power pup,i was told it could be updateable if i sent it in and paid the 100 fee.it didnt make much power so i sold it.i would like to try a pmt.they seem pretty sweet

There's a tow stacker as well. Each engine runs different. Maybe yours won't be noisy with puck and non stacker tune. Try and see. I think the 100 hp tune runs lots of timing for milage.

The bullydog I had was for a 03-04 and that's it. Couldn't be modified for newer models. Sell ur 7130 and get a 7131 not a big deal. Their cheap enough.

i hope its not the vp44.i had a 02 and my vp started acting up.it would come and go but i knew it would eventouly pack it in.does he have it chipped at all

mine has been doing it ever since i can remember.mines a standard and my dads a standard too.try a diferent tune or even a stacker tune.i know the stacker tunes dont raise rail pres but one of them may suit ur truck beter.i run the rkl with no timming added.i dont notice the rattle near as much if ...

well im not a diesel fanatic but i can aswer ur question.its called timming rattle.its caused by the fact most programmers advance the injection timming.some more than others.mine does it and my dads does it,seems more noticable on a standard trans.i dont know excactly why it happens but i dont ...

ya the autos have slightly smaller turbo which may spool a lil faster so u dont see any smoke,thats a good thing,the rattle ur hearing is the tune advancing the injector timming,i think u can download a non timming version of the performance tune,i personally dont run timming at all.im running the ...

ya running perfprmance or tow or even extreme the rail pres doesnt seem any higher than stock.i have a rail gauge and ive tried every tune offered for the pred.

i found the adapter cable at london drugs for about 10buks,try staples too.cheap cables there,if he didnt put it bak to stok before selling to u u may have a prob

i dont think any tunes emit smoke at idle,no smoke is a good thing,u are burning the fuel efficently,try exreme for some smoke is urs a stik or auto,one of them has a slightly difernt turbo which may act diferntly with tunes

i have a rail guage and i dont see a diference in rail pres with the pred.i dont have a puk.i run a quad x2 for rail pres.i dont add any pres in the winter months for fear of injector issues with cold thick fuel

I've had the pred alone for almost 3years and it's mostly been on rkl no timing. I've smoked the tires a dew times and smoked out the block but mostly drove normal and clutch seems fine and truck runs great and gets great milage. I have no complaints

Try a different tune and see if it does it. Does it throw any codes when it surges

Ya for economy try the performance tune and use the puck for an added kick or to get a load rolling. I get best milage from the rkl without timing but I drive like a grandma haha

That's a great deal. I think u would have better luck on eBay or castanet. Most guys here already have a pred that's why their on here.
