how about the shift points, anyone edit those?

 

Fatherford did and i think he knows the feeling he's after. I'm learning this part myself so i'll be watchin.

 

you guys are gonna wear your trannies out setting the pressure too high on your stock transmissions trust me. You need a modded transmission to safely handle that, its too bad the J-Mod doesnt work for the 04 F150s because they dont use the 4r70w transmission.

 

Oh well when it wears out ill rebuild it better. Pay to play

 

please everyone 20 psi of pressure is not going to destroy the tranny. also gregg evans told me his ftvb for the 4R70W is compatible to this tranny as the snail pattern is more or less the same :0

 

Does anyone know what the superchips shift pressure is? I mean say I set it to +12...how do i know the superchips setting isn't already +12..or is the superchips around 20??

 

Remember that your shift will change A LOT after 100 or so miles. Easy to get it just right, then 100 miles later it may be too firm.

I set my Superchips to 12 and was very happy with the settings. 16 lbs works well if you are a hot-rodder. Twenty would be a bit rough grocery shopping. The Superchips seem to be about 18-20 on tune.

With the Diablo it leaves your shift stock unless you tweak it, and stock is lousy.

I set my DP for 120 percent. I wish the two companies would use the same nomenclature...

The 120 percent was fine, but after about 600 miles it starts to feel a little too firm. I get second gear chirps if I'm in a turn or on slick asphalt. That is at half throttle.

Next time I tune it down I'm going to try 100% and just expect it to change over the miles.
