SleepyTuned's own Hyundai Sonata N-Line 2.5T development car, from the rear

Our development car

We don't tune a platform we don't own.
So we bought one.

Our own Sonata N-Line 2.5T is the development car. Every 2.5T file is built and tested on it first.

The 2.5T lineup

Your car's on the list.

What you get

Everything in the box.

  • Your 2.5T ECU tune
  • Pops, bangs & burbles
  • Boost control
  • Optimal fuel control
  • Launch control, added to the N-Line

  • Spare ECU ships to you pre-flashed

After checkout we'll send you a short form for your car's details, then deliver your tune.

When do I get it?

After checkout we'll send you a short form for your car's details, then deliver your tune. Spare ECU can take longer to ship than remote tuning because each unit has to be flashed on the bench.

Which cars?

Genesis G70 2.5T, Kia Stinger GT-Line 2.5T, Kia K5 GT 2.5T, Hyundai Sonata N-Line 2.5T, Hyundai Santa Fe 2.5T, Hyundai Santa Cruz 2.5T, Genesis GV70 2.5T and Genesis GV80 2.5T.

Remote flash or spare ECU?

Remote flash ($495): your tune, delivered remotely. Or Spare ECU ($1,495 total): a spare ECU shipped to you, pre-flashed with your tune. Plug it in and keep your original ECU untouched. Both include pops, bangs & burbles, boost control, optimal fuel control, launch control, added to the N-Line and hybrid turbo cars supported.
