Just did this. Completely stock car, and I'm in Cali, so had to go for the lowest tune. After a 10' drive around the block, the car feels more immediate. Unsure if there's any additional power (maybe 10% tops?), but the delivery is way better. I flashed with the burble on medium, maybe I should go for high. Even at medium is better than the stock level... for what I can remember, similar to a 35is?

What options did you guys use with the flash? I just limited 1st and 2nd gear, and put burble on medium. Curious about the options.

Flash took around 40 minutes, forgot to turn off the fan (but the AC was off). Used a trickle charger. Also did not turn ignition on the first time (just inserted key), and the car did NOT like that. But solved it very easily by re-attempting the flash with ignition on (but engine off).

Recommended? Possibly. The price is attractive enough and it's a very simple thing to do...
