I'm thinking about buying a set of Comp Cams Stage 2 XFI NSR cams for my 06 GT. According to Comp Cam's web site "Works with tuners, no computer re-tuning required." I'm running a Steeda CAI with high inlet tube and a Steeda high octane tune. I also have JBA Cat4Ward headers installed. Is it really OK to run these cams without a tune update? I eventually want to get a dyno tune after I'm finished with the engine mods and don't want to spend the extra money on another e-mail tune. Since I'll probably buy the cams from Brenspeed, I'll have to purchase a tune from them if required. The Steeda tune is great (came with the CAI purchased direct from Steeda), but to my knowledge they don't update them as you add more mods.
