must have had same thoughts as I did,
spend less up front with the V6, (I'm commuting for work so wanted fun and MPG) then mod it some with bolt on bits.
Good option for me as I do my own work!
I did NOT like the BBK Throttle Body (but admit I have not installed a TUNE with that.) I lost 2 ~ 4 MPG with the 73mm upgrade to the TB. I was averaging 32~34 prior to that 73mm T.B. (with a tune, MF 19099 cat back, AirRaid CAI & using the SCT4+ Tuner & free BAMA Tunes.
I also just installed more mods over winter and built a radiator guard made from Menards metal in behind the grill as my Air Con condenser was clogged with bugs/gravel and show damage dut to big grill openings.
