Anything over the 400-425 mark is extremely questionable on a stock mod motor. 2 of my best friends had 425 - VERY VERY safe tunes. 1 year later they were both buying new engines.
100 isn't SO bad. Get it dynoed and see what a 75 puts down and then decide. Make your decision based on the RWHP # and stay under 425. That's my suggestion.
Your A/F should be in the 11.4:1 to 11.6:1 range.
So I guess I should spray a 25 shot then,lol. Maybe 100 shot will last? who knows.
