From "stay tuned" to T U N E D !!

Is there any reason why you keep going back to this company?

At some point you just need to move on. You've tried all sorts of combinations so far to resolve the issues, but nothing seems to work. To me it sounds like the tune itself is flawed and the only way to truly figure out what is going on is to do some deep data logging and analysis, which is a dark art in itself and nothing something you should have to do to find the error in someone else's software.

Personally, this would be the point where I'd scratch it up as a loss and start saving up to try someone else's tune.

Another thought. If you still are interested in a tune, are there any local places that will do a custom tune based on your other mods? The options might be fewer compared to those places tuning GM, MOPAR, or VAG vehicles, but it might be worth looking.
 
Yeah I bought the initial tune for $1100, on a brand new, spare ecu. That one didn't have this issue but was taken by the dealership when the 2nd knock sensor issue came up, replaced with new ecu, so I was able to send the original one back and reflashed for free. I know what your saying about going back

As far as local tuner, noones into Korean cars

My buddy wants to double check the "gap service" my tuner offered me, I mean it did break up on the dyno with the 1st tuned ecu and then random partial throttle issues, could you imagine IF gap was the problem
