Kzang my friend had JB4 and it melted his battery cables twice, he has Racechip now .. Like it has been said none of these piggyback are 100% they all react different on each engine. But the recommended is if you want less likely issues you can get a stage1 tune (aFe scorcher, racechip "stock setting", bms stage 1, etc)
My friend had BMS Stage1 and he was getting drivetrain malfunction at least 3-4x a week he was so tired of it and couldn't get a fix on the forum he sold it. Drivetrain malfunction happen with or without the tune, but seems for him it was cause of it.

I've tried my RC on my petrol engine on extreme levels in the winter and also in my last Dynojet but in warm temps I wouldn't increase mine above F since its already 3 ticks above stock. Also, 42pilot have you asked Racechip Germany?

So all in all the same way a certain map wont run as well for someone with JB4, same goes with RC setting. Trojanlaw I remember that pic
