Nitrous and tunning

The thing about returning you timing to base is that the stock timing is already retarted from making peak power so you don't need to retard it more with only a 75 shot htat the ZEX is giving you . Once you get it all sorted out you may even be able to put a little timing back into it but i wouldn't risk it until you are sure that everything is working good then maybe adcance it one degree at a time.
