I replaced my Troyer 91 tune with the VMP custom 91 tune in my Expedition. I had detonation off idle and had to retard the timing 6 degrees to get it to not detonate with the Troyer tune. The VMP tune so far has a better idle and pulls better. Thanks Justin for the tune and the great service

 

That's always good to hear !!

Any pictures of your Expy?

 

the tune you had a troyers, was it canned or custom?

 

custom and I even had data loged on the dyno.

 

Wow.

 

Just recently bought and installed (approx.2 weeks now) sct x3 w/vmp tunes I have to say I'm real happy with the performance of the truck even though I've only loaded the 87% eco tune thus far. I've got improvement a mile or 2 being honest I thought I would have gotton more, but I probably set my expectations to high. but like I said the shift points are noticably smoother and there is better throttle responce (probably the reason I only got a mile or two ) and haven't nock on wood set off any codes loaded right up no problems I will be trying performance tune soon
