I'm pretty good with my 6sp, Can't drive it like a drag racer and if I do play speed racer, it eats flue, 2nd gear to 3rd is arround 1500 Rpm, 4 th gear 2000 Rpm, 5th around 1500 Rpm, 6th gear 2000 Rpm.

City MPG has never been good, as to be expected, once the truck is in 4rth gear, it really can move betwen 3500 and 4000 RPM, all the wy to 6th, but than it eats flue...

I would like to get rid of what ever holds the RPMs at a 1000 Rpm when shifting gears ( if you go over 500 Rpm )

 

I have the superchips 3865 and like it. No real increase in mpg but shifts better and a little more power.

 

The factory tunes them a tad rich and low on timing to be safe for people why do not use the proper grades of fuel. It keeps engines together by reducing the possibility of detonation, even though it can happen on a Hemi running 87 octane. Manual recommends 89 for the Hemi.

 

I own a 6sp manual, I have never ever killed a clutch, but I have killed automatics, ( dodge, ford and GM T350 ) I will control the shifting, How much H/P is a tunner ( brand type ) really going to give in the real world?

I all ready have a true dual ex, low end torque is down a bit, but I have a real torquy 6 sp, on the highway, My truck all ready has more highway power and top end than any 3/4 ton needs.

I don't know the exact **** ratios for each gear in the 6sp, rear diff is a 373 ltd slip, and you could have a 500 H/P engine in my truck and with the 6sp, is still not a drag racer, I would like to improve my city mpg, can this be done with a tunner, thiers no shift paterns to adjust.

Is the tunner going to know I have dual ex all ready, and if i Add a cold air intake kit, is a tunner able to adjust setting's to take advantage of my mods, or is just a modification of a 100% stock truck.

 

I dkn't think Diablosport has one for the 2500. Not sure, but on the 1500 Hemi, it is a 20rwhp gain as well as 20 lb/ft to the rear wheels. Not too shabby!!
