I have a 2007 Mega Cab 4x4 5.9 with 37's. I have run Edge Juice w/ Attitude, Superchips, and Smarty. I ran the same ones on my 06 Mega cab and liked the Superchips power way above the rest. It was very responsive and had a lot of top end pull. But I guess they don't have that program around anymore and they have detuned the performance tune 30HP or so which made a significant difference. The EJA was ok all the way around. Nothing crazy but pretty even power. The Smarty has a ton of throttle response but nothing up top. It is just like a tractor. It seems to really run out on the top end and doesn't pull and put you back in the seat. I even ran the beta version and it was better but my tranny didn't like that and had to be replaced which was somewhat expected. I know there are a lot of big fans of the Smarty but it seems to be more of a tuner/ high mod programmer than something you can run stock or with a few mods? It just isn't very even power. I had a 6.0L Powerstroke and stock it was a dog but with a sctflash chip in it, it was the biggest difference of any chipped truck I have run. That thing pulled like a jet and kept going. I guess sctflash is coming out with a programmer for our Dodges at the end of the year. Any advice on the best top end setup for a 07?

 

TST is probably the best up top...maybe the quad x2? That being said, the smarty beta 4.4 has a great top end, and is less touchy down low like the stock smarty software....beef up your trans and use the 4.4...esp if you still own the smarty.

 

you really thought the flashpaq was the best tuner-better than smarty and edge- really... really?

 

Sounds to me like you need to get more fuel to the engine if you want that top end power back. Do you have a fuel or rail pressure guage? Stock lift pump?

 

No, I don't have a fuel pressure guage. Yes, I realize I should get more fuel but that is why I am saying it might be better for a non-stock setup like my Superchips was. That thing pulled great and I didn't have to change anything. I might try it one more time with the Beta on 9. Supposadly that is the best running setting and 1-9 aren't much difference?
