I have it on my 92 mustang, it's a carb not efi though. First thing you need to know is what engine is in your truck, is it carb or efi? Unless you've had an engine swap your truck will most likely have a cast piston and not a forged piston. I wouldn't run over a 100 shot on a cast piston or your asking for trouble. Here are your basics.
Are you planning on using a wet system or dry system if your truck is efi?
Lower timing I always start around 10°
Good fuel is a must
Anything over a 100 shot will require more fuel pressure on a efi car/truck.
Bottle pressure, I usually run around 900
I recommend a purge valve (money well spent)
Cold plugs I run a gap of .38 to .40 Depending on weather.
DO NOT HIT THE REV LIMITER
DO NOT MISS GEARS IF USING MANUAL TRANS. WHILE SPRAYING NITROUS
If using for the first time I'd recommend using a micro switch so it only activates at wo throttle once you master it you can change to a button.
I have a 250 shot on my mustang and haven't had any issues but I have forged pistons ?
I'd find someone at your local track that can help you choose what's best for you and your truck and also give you advice on using it.
ONE THING TO KEEP IN MIND IF YOUR TUNE IS OFF OR YOU MAKE A MISTAKE IT CAN BE CATASTROPHIC!!
