Hi all, I'm looking for a tuner (East Midlands or UK-wide) who has tuned the JB-DET before. My car is a 2006 L880K JDM import, 659cc JB-DET, [5MT/4AT], [mileage], stock ECU, running 98 RON. Mods: 71°C low-temp thermostat, straight-through BeFree exhaust, D-Sport air filter and an intercooler with about 180% of stock capacity. I want a tune that accounts for those parts, with engine health first: wideband-verified AFR (around 11-11.5:1 at full boost), conservative timing, boost at 0.9 bar or below, and coolant-temp compensation sorted for the cooler thermostat. I'd rather have a safe 80-90 hp than an edge-of-detonation peak. Has anyone in the UK had a custom remap or dyno tune on an L880K, and who did it and what did it cost? For D-Sport or Unichip users, did you need any changes after fitting a bigger intercooler and free-flow exhaust? Can anyone recommend a rolling road in Leicestershire, Derbyshire or Notts that will tune a kei turbo and log AFR? I'll share dyno sheets and the method afterwards. Thanks!
