Hey guys I have a question, If I have a stuck egr valve can I run egr delete tunes without hurting anything? thanks for any and all info. btw its a 08 6.4 Spartan tuner, full 4" exhaust downpipe back, cold air intake.
You should have no problem running a NEGR (No EGR Spartan tune) with a connected EGR valve. The tune simply ignores the EGR altogether. I've seen NEGR tunes work perfectly on trucks with fully installed/operational EGR systems.
