How can I get aftermarket tunning support for my Middle East Commodor Sedan?! I had someone tune it for me, and after checking what he did, he only changed the timing curves... nothing else... no fuel nor air flow, so what I need exactly now is support in this... (ps: we have no dynos here, but Im getting a wideband soon)

Thanks, please confirm if HP tuners gives us aftermarket support on tuning!
