Zach at CSG has been great with me.
Initial communication in December and his initial 94 tune came within days of online order/payment.
Subsequently, my return logs were promptly answered with revised tunes over-night until complete. In total 5 maps got us done.
Last week we where in touch and he sent me a second map for 91 to be used when 94 was un-available. Which is common away from the populated areas in Ontario.
