My Whipple was installed on my bone stock '14 R/T AWD by National Speed in Richmond, VA, the same company that's located in Wilmington. Nice people. Big, clean shop, and lots of nice cars, including MOPARS.
My engine grenaded 7000 miles later, well within their warranty period. A rod broke and the block was punctured in two places, along with the oil pan.
They maintain that it's not a warranty issue; that the rod breaking was due to a preexisting problem. Which could well be true. I'll never know, as I'm not willing to go to court over this.
Since they have the car apart, switching to another shop isn't a practical option for me. So they are going to put in a forged short block and some other stuff. I believe they are basically competent at what they do; this may have been a one-off event.
But I'm seriously considering taking it to another shop after it's done, and paying them to check it out, including the tune.
As for doing mods in the future, I will seriously consider other shops including Steve White Motors in NC, even though they are all significantly farther away than NS. After this experience, 'close to home' is now a much less important factor in choosing a shop, for me.
Good luck with your mods.
