Superchip for 5.9L
I've read a bunch of posts on the superchip for Hemi's, but is there anyone out there who have used it on the 5.9L. Are the results worth the cash? The best price I've found so far is $299. This will probably be the last mod I'm able to do in a while. Just got the cat back. And the explanation to my wife..." it will improve gas mileage"... won't work much longer. So, this needs to hold me for awhile. Thanks
I guess nobody has used it on 5.9L. I went ahead and got it. I put some 93 Octane in today and tuned the "performance" program. Strangely enough, it seems like I had more grunt when I had it tuned to the "87 Octane" program. I haven't had a chance to try the "tow/ haul" program. I will say when I first tuned it to the "87 Octane" program it felt like the engine finally got it's ***** to drop. Much better than stock.
