D15B with Neptune RTP
Hey guys I got my Neptune setup about 2 weeks ago and am on my second tank. The first LEAN burn attempt was 38mpg. Not as good as Ive seen people getting. my 2nd tank looks to getting a lot better. Im at 240 miles and the gas gauge is at almost half tank. Is there someone here that can read my tune and give me some pointers? and also what should i change? like Disable Closed Loop, fan control in gauge at 180 above 50mph ext.... any thoughts are greatly appreciated. Thanks
