had my car tuned last September of 09 and i have made a decent amount of changes since then and am not sure if i should be retuning for the changes or not.

the original tune made 301 whp and 305 wtq, since then i have made these changes:
-swapped upper charge piping from dejon to injen
-swapped intake from Dejon SRI to Injen cold air
-added a cherry bomb glasspack to the mid pipe of the side exit exhaust

i asked for a slightly mild tune originally (although the gains were enormous went from 243 whp and 228 wtq to 301 and 305 repsectively), but ive been wondering with the changes i have made if it would be better for me to have my car retuned for the new mods. i know it couldn't hurt, but is it something i should definitely plan on doing soon?

 

It might be a good idea simply based on the fact that you went from a short ram to a cai. I actually did the same sort of swap at one point and BOY did my MAF need recalibrating. My trims were all sorts of whacky from the swap.
