I believe the 264's with a healthy lope pull around 12-14"

If you upgrade springs, use the same manufacturer (tomei cam = tomei springs) as a general rule for sr20 engines.
Thank you for your help!!

I've checked the timing MULTIPLE times and rechecked the teeth count on the cam gears and everything looks good to me.

Are there any quick tests or ANY tests i can do to validate my timing is correct other than my timing gun and counting the number of links on the chain between the two points on the cam-shafts?

I have it tuned to run at around 17 PSI and it holds great and doesn't break up or lose spark. Also running at around 11.8 - 12.4 AFR under WOT runs.
