For those of you guys who have no cats on your truck, where are you purchasing your o2 simulators from i am trying to find them on the sponsor sites with no luck.

 

just delete your rear o2 sensors

 

custom tune takes them out, or get the ones that come from a f-body (camaro) they're a square type plug.

 

I got mine from Allen Nelson @ NelsonPerformance in the way of a custom tune! Just get a Tuner to delete the rear o2's.......from what I've found out....the industry has quit manufacturing o2 Simulators because it DOES violate a federal mandate on modification to a federal emmision control device....blah,blah....blah...

 

A simple way is to get a Mail Order Tune from Wait4me... i think its bout $80 or so...
Last time i checked O2 Sims were $30 each? Whats $20 more for alot more??

 

how do mail order tunes work? do i have to send them my stock pcm or something?

 

That or they'll send you a replacement, and charge you a core until you return yours.

PM wheatley, he's a great tuner on this board with great feed back.
