it runs right around 14.7 when cruising which is acceptable. i have two different 740 chips, with varying latency, and they both had me running lean across the board. i contact deatsch and they say the tune is the culprit and that they would send the necessary specs to the tuner(not sure if they ever talked to each other). i had a very hard time getting answers from mike at deatsch and getting email replies. i contact the tuner and he says that i probably got the wrong injectors and is wondering what is wrong since another car with the same injectors runs perfectly on the chip....well not in my case. he also sent me a 555 chip to see if that was better, and in my opinion the car is a little slower, but less prone to detonate. yes its rich in the upper rpm band, but comfortable low to mid range. so i have to suffer with that til i get intercoolers and recheck the chip, get nistune and adjust the values myself, etc.
