i put a skunk2 on my gsr and lost lot off lowend power is there any way to get some of this power back..i was told to change from obd2 to a p28 and that would bring back some of the power?

 

get a chipped p28 and some type of ems and tune it.

 

if your still running that gsr p72 ecu w/ the skunk2 IM, then your not fully benefiting from the modification. Do look into getting a chipped p28 if you have some mods that'll back it up. Check out my vouch thread.....the guy who dynoed my gsr posted up my dyno graph (shows the stock ecu vs my custom all motor programmed chipped p28 ecu). The mods i had on my car at the time were aem sri, skunk2 IM, ctr intake cam, dc 4-2-1, test pipe, and greddy sp cat back....as you can see, the stock ecu was hurting me bad!!!! PM me if you have any questions
