Title: EGR keep or delete
Post by: Shimy87 on October 02 2014, 10:32:57 AM: While I'm working on this, whats the scoop. TT chip dosent use it, can I make a block off plate or should i just keep it where it is?

Also want to clean up some things. I dont use the wastegate soliniod, if I unplug that will it throw a code? Same question on the EGR soliniod. If i can eliminate them and just hide the plugs it would clean up the look but I dont want it to screw something up.

Thanks!!

No problem removing the solenoids. Code is disabled in the chip

If it doesn't rob horsepower, and saves fuel at idle, what's the harm?

Post by: tb3 on October 03 2014, 09:52:03 PM: Oh yeah! Cruise. .
that's what I meant.....lol!
makes sense to me then.
Thanks Steve! :cheers:

and yes it is ugly.
I left the brass plug in mine from the earl brown mod and put the egr back on to dummy it for stock appearing

Thats the way i will go if i ever pull my intake manifold off
