I installed the Hughs Plenum pan and gasket about a year and half ago in mine. I think my problem is more fuel related. I should know for sure in a couple of weeks after I am sure all the bad gas is gone. If not, I will try cooler plugs.

 

had the hypertech max energy,now have the superchip 3815 and havent had pinging with either one.93 octane is what i always use.better fuel economy with the max energy.better power with the 3815.both on performance setting.

trucklover...can you post up a pic of your power wire installed? i have bee thinking about one.are they any good?

 

It is supposed to increase power at WOT, but I really can't tell that much difference with it. Maybe I just got used to it. I may try disconnecting it and resetting the computer and see if there is any difference.

 

Talon6, have you tried downloading and installing the mileage XS program? It says that it is only for the hemi, but I downloaded and actually installed it. I figured it would give me an error message but it didn't. It is not as powerful as the performance tune but the truck had more pep than with the 87 or towing tune. I didn't keep it on there long enough to check and see if it help the mpg's though, I missed the performance setting!

 

no i havent had mine hooked up to the pc yet.maybe i will have to try it.but i would probably be like you....back to the performance setting.lol

so you think the power wire is not worth it?

 

Honestly, I can't recommend it. It's not enough gain to justify $50 or whatever it costs now. On a different model truck you may get different results. I have read on the 4.7L engines it makes a big difference. But, I have also read on a forum that the guy who sells this product recommends resetting the computer every 500 miles or so to get the most benefit out of it.

 

10-4. guess i better overlook that mod.thanks for your input. if you happen to unhook it sometime and run without it let me know if you can tell a difference. thanks again.

 

Will do!
