I can't seem to get good mileage out of the GN. I know its stupid to worry about mileage but it is my daily right now and premium prices are killing me. Anyways I have new 60s and a chip from Eric Marshal. Everything works great. i had lean cruise added in but on a mostly highway trip (75% highway) i still can't seem to get more than 16 mpg or so. Am i asking too much? I have been having a low blm problem as well.(with the 50s as well as 60s) While cruising it drops to 110 or so. (i know this is still within range) While idling its around 116-120 and at WOT it locks at 128. fuel pressure is 43 line off. If i move the translator to 10% lean the car runs really bad. Any ideas? Lean cruise is working and the TCC is locking and both switches in the tranny are working. Am I just expecting too much out of a car with 60s and a 3200? There are no exhaust leaks at all. I'm sure if i absolutly babied it with 0 psi the whole trip i could maybe eek 17-17.5 mpg out of it, but thats hard to do with a big stall and a small turbo.
