Good no2 kit?
As far as gains,bump the jet until your happy. Some mfg's rate at the wheels and the others at the crank. Its just a matter of changing jets to suit your needs.
Along with you wanting a bottle opener and bracket, I would also suggest a few other accessories to go along with your kit. Things such as a window switch, filter, blowdown, spark plugs, heater, purge, etc. are all great accessories designed to help keep things safe and in check as well as consistent. We sell it all, along with nitrous kits. If you have any questions, give us a call or feel free to shoot me an email or PM.
Thanks.
Nick

It sounds like you would benefit hugely from reading the stickies first before posting questions.
