Mich - With all these great experts laying it all out for us...how can we go wrong??!!!
Havent installed mine yet..but seems that both are relatively easy mods.
Got my Boost Controller from an eBay seller that happen to have a warehouse in my area...no shipping or sales tax for $195.
I got a TurboXS like Deez92, but mine is a Dual Stage, able to be switched between boost settings from inside the cabin.
Ordered my gauges from RPMoutlet.com.
They seemed to be the only ones with an Autometer "Lunar Series" Pyrometer.
JCWhitney, Jegs's, SummitRacing and a ton of others have gauges on the web.
I went with the Lunar...according to Ripster they match the PTs dash colors perfectly..plus the pics I saw looked SO COOL like indiglo...extra $$ tho.
I gotta Boost and Pyrometer, maybe ill add an Air/Fuel Ratio in the future.
Good Luck!!
Rob
