What is the Best Handheld tuner out there?

[Firebird1]

Hello,

I have a 2010 Camaro SS 6.2l, the care is 11 years old and I have the extended warranty on it but after this warranty expires Im not getting another one. I had issues with ENDURANCE(MEPCO) of covering things. But anyway What is the best handheld Tuner out there onthe market for these cars.There is no tuner in my area(location) I asked the dealer to do it. because I put in aftermarket part like new coils, plugs and wires new 3 row aluminum radiator, SS lower radiator pipe and 160 degree thomstat. I also install accent dash lighting and a glove box kit kit. In the Spring i Think i will be installing long tube headers and 3' exhaust system with high flow Cats.

I bought the care used with a cold air kit installed and head light changed. The Tuners I was looking at Diablo sport Predator P2 7201 and the Bullydog. Any opinions on which tuner is the best? Thank you in Advance.
