in my opinion it is. For $500 more you get a tune that is customised to your specific setup. There's no risk of your ecu being fried and having no car for a week either. You can also remove it and sell it at anytime to practically anyone.
I emailed Haltech a few months ago about the gains and they said you can expect about a 12kw gain with a couple of simple bolt ons or two (like an intake or a header).
Yeah i agree.too much BS associated with Jtune and the reflash is now $1195???Hmmm,Haltech is tempting.Is that 12kw at the wheels?
