the temperature and humidity along w/ the a/f mixture mostly likely flucuating from your last dyno will negate any noticable difference on a mod like that, so dont beat urself up if you see the number even dip a lil. Just my .02
 
255/290 on a MUSTANG with just those mods? Would you mind posting the dyno sheet?

Theres a link to near exact number and similar mods...

This pic is a comparison between runs after some mod changes, gonna have to click the link for the mods for each run cause I don't feel like typing it all
 
I went from 228 rwhp / 262 rwtq, to 239 rwhp / 276r rwtq with my Accufab combo.

One month later on a slightly cooler day at a different shop the reading was
243rwhp / 285rwtq. No mod changes between the runs at the second shop.
Better operator, slightly cooler, computer learned the new set up?
 
the only way to honestly compare numbers is to run at the same shop on the same machine, at the same temprature, preferably on the same day.

Realistically all we can hope for is same shop and similar temps.
