Better to have the car logged and propperly setup though rather than a generic flash though?
It's convenient to drive in, wait an hour or so for the flash and drive out but you tend to get a bit more out of the custom map & know that it's safe and tailored to get the most from your setup as it's all logged on the dyno / road.
Either way stage one is great and one of the best value for money power increase mods!
Might get a chance to meet up as I'm heading to R-Tech for a custom stage2+ file when my hybrid turbo arrives :)
