Hey Tim , ifyou havent made your mind up I just had village ford install my spec2+,fidenza aluminun flywheel, foire adj.quad, and and new cable with ldc freeplay kit. Im at 450 hp and this clutch graps hard but chatter is almost completely gone. BE happy to let you drive mine if you havent made up your mind. I highly recomend it.
My 3+ is very grabby. It chatters a bunch in 1st and reverse, and it chatters every now and then when I down shift. Nothing too bad, I have gotten used to it. It grabs and holds like no ones business though. During break in it was very on/off and even after about 800 miles, it still has some on/off tendencies to it. I just had to adjust my driving style a little.
Why would you go from a Ram HD to a SPec 3+?
