Been saving up for months and I'm finally ready to pull the trigger on a proper tune for my 2017 Focus RS. The car is mostly stock except for an intake and catback, but the factory calibration feels so jerky in sport mode and I've read too many horror stories about LSPI on these motors. I want someone who will actually listen to my concerns instead of just trying to squeeze out peak numbers for social media. I found https:dynostarworkshop.com while searching for local dyno options and the setup looks serious, but I'm a bit nervous because this is my first time getting a car mapped. What kind of questions should I ask before handing over the keys? Like, do I need to ask about their cooling setup during pulls, or how many miles they typically run on the dyno for a custom calibration? Also, if anyone has tuned an RS here, did you notice the low speed drivability improve or did it get worse? Really appreciate any advice from people who've been through this before.
