Going on past experience with the 6.4 and custom tune I got an extra 55kw, or 74hp.How much does a custom tune with programmer and PCM cost? How much gain?
Thats with magnaflow cat back and intake.
Sent my pcm to tuner and had tune installed for $500....
This was before they had cracked any of the 6.4 pcms and they had to write to it directly.
Exhaust and intake around 1100.
I've never been a fan of piggyback ecus in petrol vehicles, they always seem to be a compromise. I've always had better results with stock ecu tuned.
I'll be interested in how they deal with mds....
I've used steinbauer piggybacks on big rigs with good results.
