OK 16 RAM Sport 5.7 4x4 no lift - stock tires as of now - I am considering a Throttle Body, Power-Plus Series, TBI, 90.00mm, Cast Aluminum, Natural, Dodge, 5.7L .... also a throttle body spacer and the mopar designed Ram Air Intake kit / CAI that will work with my sport hood - I would like to know of anyone's experiences with any of these - I am particularly interested in the throttle body spacer and larger TBI - like the BBK 90 or 87 mm - any real improvements? Would I need to get a tune? maybe a flow-master 40 to breather easier? how important are headers? just want to spice it up a little but more - its nice now ... this 5.7 hemi seems like its on the edge of some real potential... - basically I'm interested in things other than opening up the young engine - other than camming etc... I would love to know anyone's experience with any of these upgrades problem's or success... fact or fiction ... help a RAM brother out here ... Thanks & Love Y'all . . .
Don't waste your money on a throttle body spacer, it is just a paper weight, they are designed to help optimize the incoming fuel, since the 5.7 is fuel injected in the heads, only air flows thru the throttle body. If you want to run a 90mm throttle body you will need additional mods to include a quality tuner. I never seen the need for anything larger than a 87mm throttle body on a mildly modded street truck. Modifying the exhaust would also help, an engine is an air pump so as more air goes into the engine that additional air needs an improved exhaust system.
