I did but....I got the DIY SMC Kit headbang
instead. Just seemed quicker and easier at the time. After seeing it now I think it would be simple enough to put one together. I was going to put one together for a friend of mine but he was too tight for even the DIY.
As for tuning I think you can run into problems if it comes on too early or if you have a dual nozzle like me you may spray enough to get some traces in the motor. I can't say running wide open like you say your DIY 60 PSI setup does can be optimum for the full range. To get the most power I imagine some tuning with a EGT would go a long way too. I think typically the EGT sweet spot with alcohol is about 100 degrees lower isn't it?
