Hi this is my first post and I need some help. I have a 2000 ram 1500 with a 5.9 with 183,000 miles on it. I have added a few mods like headers, magnaflow cat, cherrybomb extreme muffler, cold air intake, and hypertech tuner. I want to add a mopar performance intake and bigger throtle body, edelbrock performer heads, and a new cam and lifters.
My question is how big of cam can I go without having to retune the cpm. thanks for your help in advance.

 

With the changes you are making, you will need a retune in any event. Best bet would be to contact Hemifever and ask his advice.
