Brian doesn’t tune Diesel. Never has. Has no plans to either.
You cannot delete dpf, def, or egr without a tune. It will not run without those items unless tuned.
$2500 seems high. The Exhaust is 383 shipped from Thoroughbred Diesel.
Egr delete will run you $60-$160 depending on your choice.
Tuner and tunes will be $1000 +\- again depending on choice.
EZLynk is my choice and what I’ve used with excellent results.
EFi Live a close second.
I’m not sure what their options and prices are for Ford 6.7 though as I’ve not personally done one of those yet.
Ive done Cummins 6.7, Ford 7.3 and 6.4 and Duramax.
