dude you dont have to put your car on a dyno....I have a stock crx that ive been spraying on now for about 6 mounths...with a 50 shot i have seriously gone through at least 30 bottles and not one problem yet. And the stock motor has over 200,000 miles...
Dude for real just to be safe just retard the timing a little and you will be fine..My timing is at 16 degress advanced and i didnt touch the fuel pressure..If you are useing a wet kit just retard the timing a little..Test it out ...if it runs good and no detination start advancing the timing a little at a time...You really dont need to spend all the extra money on a dyno just trying to tune nos on a pritty much stock motor..And i would advise not to spray anywhere before 3,000 rpm's...spray after 3,000 and keep spraying to your shift point..well i hope this helps you out a little..Good luck..
