I just bought a few bolt-on's for my car: C&L CAI, GT500 TB, and some CMDP's. I'm planning on getting a new email tune from The Diablo Shop to accommodate the new goodies, but I'm also planning on getting some LT's and an offroad H-pipe installed in the next month or so. If I request the rear O2's to be turned off in the tune, will I need a new tune with the LT's? Or would it be better in the long run to get a tune this week and tell them I'm running LT's?

Thanks, guys!

You will need a tune for the parts you have now and you then you will need to get one for the LT's. IMO get a mid pipe with cats, recent federal mandate prohibits performance shops from turning off the rear o2's so legitimate tuners will not turn them off so unless you know a shady tuner you'll need cats.
