For clarity purpose 4 credits are needed for auto transmissions. Manuals do not require credits in HP Tuners.Actually HP tuners is running a promotion where the PCM unlock service ($250) is complementary with purchase of either their interface or 6 universal credits (2 credits are need for PCM and 4 are needed for TCM - credits cost ~$50 per credit).
I've thought about switching to HP tuning, but I have no idea how long it would take to get up to speed (no pun intended). The basic course is $500.00, plus the cost of good books to learn everything, and with my mods, it's nothing for a tyro like me to mess with. Like others here, I'm old...www.challengertalk.com
