Flash tune problems
So, I recently dropped off my M235xi to a local, reputable tuning shop. I discussed many things with them as I'm fairly conservative in my desires to seriously modify the car. A Dinan Stage 2 seems intriguing, though the cost is difficult to justify for the minimal gains. I added a Fabspeed Sport Cat for some extra power and sound along with a Dinan muffler.
Long story short, after a few rounds of tuning, they kept running into issues: first thinking it was the plugs, so they changed them out to one-step colder. Then they thought it was bad gas...not that either. Finally they landed on the intercooler and immediate heat soak. Is this common on the car to need an upgraded intercooler before any real tuning? They said the car would run great for 1 or 2 runs, then begin to have heat issues. At the end of the day, they said they could do SOMETHING, but it would be extremely minimal and maybe not worth the cost. They recommended an upgrade to the intercooler, then do a tune. The car is now flashed back to stock, my money refunded, and me left curious to next steps. Anybody else have an experience like this?

I have BM3 stage 1 and I'm enjoying it. I do plan on upgrading the intercooler when I go to stage 2 though. I'd recommend going that route. For $50 you have access to all of their off the shelf maps while still maintaining the ability to go with a custom tune if you decide that their ots maps aren't sufficient.
