ive got a smarty downloaded on my new to me 6.7 megacab, and i was curious if i would need, or if it is needed, to install a rail shim kit, or plug? ive looked around a little bit, but havent found the exact answers im looking for..
i would f *** with it the relief i got a shim kit tried it on a d max didnt work so i put a rail plug in it and the guy sold it the 6.7 rail reliefs at 26,500
thats what i thought i had read somewhere.. cant really afford to be buying new injectors all the time, LOL.. thanks for the heads up XLR8R! ill shim the relief valve then, instead of capping it..
