Hi All
Im from South Africa and new to HP Tuners
Been struggling for ages with this (We don't have any good tuners in my area)
Can anybody look at my tune and provide feedback , I have terrible fuel consumption and poor drivability.
2008 Pontiac G8 GT A/T with a 408 stroker kit , LS9 Cam , LS3 Intake , Catless headers and full exhaust.
Thanks in advance
