where are you located? and what plans do you have for your GTO...hand held tuners are not worth the money when you can get a proper tune and get dyno numbers and see the actual improvements.
PM me your location and I will do my best to point you to a good tuner in your area...
ls1tech.com is also a great resource for tuning in your area if you look in the regional sections
