Having safety stuff built-in is the key...
Low fuel pressure switch... $25 or so?..
Won't let the shot work if fuel pressure isn't up to snuff...
Full throttle switch.. only let's the shot work at full throttle...
Window switch.. $50 or so??... You can set the rpm range the shot can activate...
3000-5500 or whatever...
2° retarded for every 50 is the basic rule.
If you have msd a adjustable start/retard is available...
You can buy a 4 speed shift knob with a momentary switch to activate all this ..
I got at least a half dozen other things if you'd like me to continue...
I was $1500-2k to do it right... And "still" haven't had the opportunity to push the button...:rolleyes:...
What it is NOT is "just throw a bottle in the trunk"... That's how dumb- dumbs have bad outcomes...:eek:...
