Sorry about asking a question that has probabaly been asked a thousand times, but what are the best settings for the new 2007 LX Charger? Also, say I go with 91 1st but then decide to switch to 87, do I have to go back to the stock setting and then to the 87 or can I go straight from 91 to 87? Thanks for your time.

My settings:
91 tune
Custom trans:
auto kick - no point in bouncing the rev limiter.
reduced TM
stock shift points
raised speed limiter - 140 should be fine.

Raised shift points are too high IMO; 6200 for the 2-3. Unless you have intake, exhaust, and cam its too high - the HEMI has just run out of power by then.

You can just re-tune for the 87. Just make sure that if you go back to the 91 tune you have just 91 or better in the tank. Maybe run a tank through before switching.
