Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
All I did to my kids jeep was change out the stock 12v battery and put in my DeWalt 18 volt drill battery. Good speed boost, but it only gets about 10 minutes run time though, but then I just change batteries.
I love the dyno part too!
