buddy has a 24v cummins/smarty and having problems..any help??

[Jonboywv12]

My buddy has a 24v like the title says, he has recently gotten a smarty programmer. the first night he had it, he hooked it up and it worked perfect. the following night he went in and changed the tune level to see what the power would feel like. Once the switch was made the truck feels like it has "less" power than it did on the orginal tune i had it on. the truck has a quadzilla programmer still on the truck but the switch is in th "off" position. could that have any effect on the programming of the smarty?? if not would you have any tips on what to maybe program the truck at on the programmer to make everything run corectly. THANKS ALOT!

I'd return it to stock. And take off the quadzilla. Then try it again.

just put the power level on the smarty back down till he has more mods. or he should buy a powerstroke sounds like the tune just demands more fuel/air than the truck will give

I know did he hook the tuner up properly?
There is a connection that goes to the "P" pump if he did not hook it up properly and it is not changing the pump timming to allow for more fuel.
I did a install one about a month ago in school with one of my classmates.

Ps this is not a cummins forum it is powerstroke forum
Just gotta to give you crap.

That's the problem that my brother ran into with his. Like other's have said, try the easiest route first and change it back to how it was and hope for the best!

What setting was he on before? What did he bump it up to? Is he running a factory lift pump? If so, I would turn the smarty down so your not stressing the stock LP cause if that lets go, it will take the VP44 injection pump (which is lubed by the fuel) with it. On side note I would get a fuel pressure gauge if I was him and keep it between 5 and 20 psi, too low the pump with starve too high and you will bust the diaphragm.

P-pump? It should be a VP44, p-pumps are totally mechanical engine. And you don't need to tap the pump like with an edge comp with a smarty I don't think.

I only worked on one cummins and it was a students may have been the vp44 on it and he put on a quadzilla that had the wire going to the pump.

If you put a programer (like the smarty) or a module (like edge comp or quad) on a Cummins it is either a VP44 24V (98.5-02) or a CR (03-07). The VE pump (1989-1993) and P-pump (1994-1998), both 12V, trucks are totally mechanical engines and don't have any electrical power adders.

What year truck is it? Did he turn the POD down? You set the POD on 00, and the truck will barely move
