I asked this before but didn't get a real answer. For a DE-K upgrade - is the Greddy or JWT ECU upgrade the best?

Slimer - that's one heck of a good little movie!

 

If by 'best' you mean something that actually does what it's supposed to do then the answer is the Emanage Ultimate. If you want an overpriced paper weight that makes the same or less power than your stock ECU, feel free to go the JWT route, especially if you want to get dumped on by poor customer service.

 

The JWT is much more then a band aid then a solution. To change the tune you have to pay and send in the ECU again. The EU you change some AFR points or timing, easy. Oh and "free" too.
