How are they? They are about 14 miles away from me. I am getting a tune from them next week. any good or bad experiances. Thanks

 

All I've ever heard was that senior is the man.

 

depends on what you have...

 

I have a 2009 f150 platinum with a 5.4 loaded. cooper 305 tires and cat back flowmaster exhaust.

 

Went to JDM today and got the tune program uploaded. Night and day. Truck response greatly improved. The gpm is steady going up, its up by 1.5 then what it was. The trans shifts down when coming to a light and the power is fantastic. I can see why people do this. I asked about the reasons for not having a separate program for towing and different ethanol and was told that the way they program, they use the training capability thats already there and add to it. The one tune will work across the board. Very impressed. Took a total of 40 min. to upload. Its a shame they can't use a universal programer to upload your tune and give you all your info on disc with out having to drop 375 for the programmer.
