I installed my SVC tune this evening. I typically don't wax poetically about this sort of thing, but I've been grinning ear to ear ever since driving it.
Below is an e-mail I just sent to Jeff which sums up my impressions:
"Jeff,
I finally installed the tune this evening and drove the truck around for about 25 minutes. I am impressed.
I was initially a bit leery about putting a tune on my Raptor, as it is my daily driver and go-to zombie apocalypse vehicle. After reading so many positive reviews on FRF, I decided to give it a try. I have had tunes on numerous vehicles I've owned over the years which include Porsches, BMWs, Nissans, Fords and more. Some were good, and others were outright terrible like the Spartan tune I had on my 6.4 Powerstroke. The performance improvement with your tune was immediately noticeable on my Raptor, but most importantly the smoothness and refinement of it are excellent. Most tuners will shoot for big numbers, but very few spend the time to really perfect the driveability of the vehicle. The throttle is responsive but not jerky, and the shifting is deliberate yet feels near factory smooth with each gear change. This is the only tune I have experienced that approaches the polish of the custom tune that I have on my Nissan GT-R. That tune was achieved after multiple revisions, data logging on the street and finally dyno testing. Suffice to say, it is clear that SVC spent a great deal of time perfecting the tuning for the Raptor before bringing it to market, and you did a superb job. Thank you."
