Not sure what you gain from the chip alone on a stock car (anyone know the answer to this question?)

miller is def the way to go imo.. havent tested first hand yet but will be soon.. in the mean time though that ebay chip i bought was the best 30$ i ever spent..

I use the MarkD 91 octane chip. Seat of the pants dynos are notoriously inaccurate but there seems to be more low and midrange power, as well as the higher rev limit - useful when you run out of revs 30' before your braking point in an autocross.

If you are going to be modifying the engine - headers, cam, etc., you will want to reprogram your ECU and the WAR chip is the way to go. My engine is basically stock so the MarkD chip works great. I also got it used for $100 so that was a plus.
