It's *probably* the UCA hitting the spring bucket, which usually isn't a problem on 02-05. Look and see it there is metal on metal contact on the spring bucket

 

I am trying to tune my 04 Ram 5.7L Magnum Hemi engine. Im a little iffy about some of the tune options. It gives me 3 options to tune. Fuel octane, tire speed, and rev limiter. I have the 93 octane tuned, the 160mph tire speed, and want to know the best option to set the rev limiter. It gives me -numbers and +numbers. I tried to s et the +500 rev but it gave me an error message. i read somewhere else I should leave rev limiter to +300, for this will shift my gears at 3,000 rpms?

 

Looking to do some engine upgrades..first thing on my mind is new throttle body. What would be best? Im in a 04 ram 1500 v8 5.7 hemi.

 

Cheapest is Fastman throttle bodies unless you want a 90mm Arlington

 

If i do a bigger throttle.. Would i need a bigger fuel pump and injectors?

 

No but if you dont run a full and open CAI to get the air in, along with the bigger TB for it to pass through and the full and open exhaust to get the exh (air) out then there really isnt a point IMO.
