Hopefully Mark didn't get Henniscrewed, but his experience is like many others that have...
* When you cut the cheque the kit is "ready to go", but suddenly there are many issues that "need ironing out" and that 4-6 week delivery turns into 6+ months. Reality is they're doing R&D on your vehicle, and hopefully he isn't using it as a parts car for things they've broken trying to build another
* "Communication" on how your build is going is mainly various marketing videos which you're encouraged to post to drum up more potential customers. Occasionally you'll get a vid of your vehicle "on the dyno" but its always chopped up into a marketing style video so you can't really get any detail from the runs.
* Customers local to Hennessey talk about what a great experience they had, customers from out of town talk about how they got screwed
John is a great marketer and hype-man, and smart enough that he doesn't crap where he lives when it comes to screwing over customers. Personally I got screwed on a "new from the factory performance ECU" for a Viper I had, which turned out to be nothing more than an ECU from a customers car that was 2 model years older and at Hennessey for a build (tracked that on the forums by matching the VIN that they never even bothered clearing from the PCM). While selling a used ECU as "factory new" was bad enough, the "tune" had the fueling so fat that it just puffed black smoke at anything more than 70% throttle. The supposed 50hp gain and better responsiveness on the track turned into a 100+hp loss with a boggy, bucking motor at 100% throttle, and having the cats overheat and melt from excessive fueling.
so the tune will automatically adjust based on the detected e85 content? what would happen if the truck was at the dealer and they reflashed the pcm as some sort of update?
