Does the check valve screw direcly into the nozzle Holder (the 90) ? This is the only way i could see it being.

Yes!

Thanks

I have the progressive control and i have no idea where the green wire goes to.... help please....

There should be instructions with the kits? are we leaving them out? Let me know so i can get onto the person who boxes up the orders.

green wire goes to the map sensor.

OTT Performance is running a group buy for your water meth kit, its specified for the cobalt and ion (supercharged), i have an 08 turbo cobalt. I want to inject based on boost, not MAF/MAP. Will this kit do that, or is it nonfunctional without being wired to the MAP? Also, will the low level tank switch, not the float switch, fit within your 2 quart tank? i don't have and can't find specs on the length to determine if it fits. THANKS

Map sensor is what reads boost. We do have a new controller with a internal map sensor coming out latter this week, It will be a tad more expensive, but will make it where you can cut a boost line put a tee in it and run it to the controller vers taking a posi lock and using it to tap into a wire.
