Nitrous kit help
Looks like your friend may have kept the instructions for himself
But Just drop us an email at dynotunesales@aol.com and we will be glad to email the instructions to you. It contains 22 pages of all the information you would need and then some. As far as the purge and heater do you need the directions for those also? If so just let us know.
Good luck with the install and if you have any questions just email us - drop us a PM - or do a search on LS1tech.com - there is a ton of great info!
