I have a 2003 durango SLT 4.7 and was wondering if anyone knows what superchip would be best. I’m trying to get the most hp and torque without spending a crazy amount. I also will be installing a K&N cold air intake soon. I’ve heard about the flashpaq and I’m kinda leaning towards that one. I’ve also heard a little about the 3715. Again, I just want the most hp and torque. Any recommendations?

 

I purchased the # 3715 used from Flea Bay and it worked VERY well the Performance mode was my choice as most people recommended it. The gain could be felt and the mileage was INSANE on a trip from MD thru Va it averaged 25.8 MPG this on a4.7 2000.
I now have a 5.9 2003 and am going to tune it as soon as becomes my driver

Good Luck

Jim

 

Oh yeah I forgot to mention that I also did hear about the 3715 on another forum but not much was told about it but I’m glad you have some input on it. Thanks Jim!

 

I was looking up the #3715 of Flea Bay but it doesn't mention the 4.7L just the 5.2 and 5.9L and the V-6 models....does it work on the 4.7L?

Thanks

Steve

 

Bumping this up again to see if anyone knows the answer.

Thanks in advance

Steve
