I have a turbo rev and it requires maintenance and tweaking, Noss is very reliable but only for short bursts most of the noss kits are good I have tried boss noss and Ice Nitrous. Both work well the ice is easier to adjust since there is not any adjusting the Boss requires some tuning.
I have an Ice Nitrous setup for sale if interested.
