I believe its just Chrysler/Mopar they give 2 shits about the performance end of the company, I have called Mopar support many times a could not get 1 question answeared, did not have a clue on thier own products, and this has been a fact for at least 25 years, just look what happen to race teams like Patterson,and several others that put millions in the Pro Stock Trucks doing R D with the R3 W8 motors, mopar made deals with thiem to develope and build motors, they bought 100s of thousands of dollars in machinary on the promise that mopar would sell their parts and Mopar pulled out leaving alot of companies in dept. I know NHRA had something to do with it also but come on. I love Mopar but I really don't know why.
