ETNOATS

Im getting a set of Steeda delete plates from a friend who went F/I. Currently I have C&L CAI, Steeda UDPs, full Mac exhaust (LTs) and 4.10s. Tunes are from AM/Bama so I get them udated free. Question is will just an updated tune be fine after the delete plates are installed or will a dyno tune be more effective? Heard these get about 10 hp gain on most cars. Is there more increase with the LTs?
