How many maps did they install?

No they didnt eliminate the oxygen sensor inputs because they said it could be a give away if taken in for warrenty work. they put in 5 maps. tuned, stock, economy, valet, and anti-theft. the rev limiter and idle rpm were left stock but the top speed limiter was removed. the timing was advanced and he told me he made it run a bit richer just because it was so lean. he told me the car comes stock tuned for 87 octane but now after the tune it is tuned for 93 octane.
the tuner told me that he was able to get the best reads in the begining and thats when he was able to do the most adjustments. he said that towards the end, due to the crazy heat, he was having less luck getting the cars numbers to respond well to changes from the tune. he told me that if i add an oil cooler and come back when its cooler they can probably do even more for me. regardless, i thought that show of 9 whp increase was good. but i know that dyno numbers are relative...
