  Please please PLEASE, for my sake, don't use a chip on a setup like that.  Not that chips are all that bad, but if you've dropped the $5,000+ on a twin turbo setup you'll want to tune it right.  Get either a piggyback controlled like the Anderson PMS or a stand alone system.  At the very least you'll want something like a Diablosport Predator or a SCT Xcalibrator.  Unlike chips, all of these products offer much better tuning capabilities and can be adjusted as needed without burning another chip.  Yes, they are initially more expensive...running anywhere from around $400 for something relatively simple like the Predator to around $600 for the PMS system.  Then again, if you even need to change your tune, you'll be spending around $200 for the first chip and another $200 for each one after that, so handheld programmers pay for themselves eventually for most people.  Just remember that, while all of these systems come with start-up programs, you'll want a professional tuner with a dyno to make the final tune.  Hope this helps.
