Lose the TB Spacer (useless on a 4G Hemi)
and get a new Fastman modded Throttle Body instead for $200.
...and pick up a Catch Can too ~$120
(I highly recommend Billet Technology)
more details on the Fastman TB and Catch Can in this thread:
...other cheap supporting mod's:
Jet 180º T-Stat (#10183) and Magnaflow Y-Pipe (#10778) for around $30~$40 ea.
The Jet takes about 15 minutes to DIY swap,
Get the Maggy Y welded in with SS Mandrel Bent pipe for a few bucks more at a performance exhaust shop, +/- $100
I also recommend you ditch the plastic engine cover (Free!) it's nothing but a huge heat trap that restricts air flow around your intake runners.
You can also delete the parasitic mechanical clutch fan (Free!) but you may want to wait for a tuner to adjust your electrical fan settings.
Then sit back and wait patiently for a Diablosport Tuner,
...the Trinity if you can afford the higher end touch screen.
(I've got the Airaid and Magnaflow CatBack too)
Great choices so you're off to a good start.
My Edge Torque Converter
and JBA Shorty Headers
are on the way (about $500 ea)
....so I expect to be pulling low 13's real soon. (already at 13.8/98.5 = 13.4/101 DA corrected)
I still have to get my custom CMR Dyno tune after header install, hopefully mid August if my parts all arrive on time.
