Is my MPG too good?
#12
Well that's good to know. I just wanted to make sure because the only foxbody guys that I know of around me have turbos in it, and I'm not there yet. Besides that, my best friend has a 91 Eagle Talon tsi (AWD turbo), so to say he knows much about foxbodys is a stretch. He helped me build this car, but certain things like this of course he would not know.

When I first got my notch, with the mods in my sig, and still had the AOD, I got a best of 28 hwy. That was corrected mpg because my speedo was off a little of from the gears, according to the GPS. Now with the T5, I can only manage 24-25 hwy. My car is in tune, and my wideband shows it's about the same ratios your pulling. I'm a touch leaner than you at WOT with 13.0.
Driving technique is "moderate" with some "old fart" mixed in there.

That is really good to know. I feel a lot better. I didn't think I was running lean or anything like that. I realize it's a 21 year old V8, but I didn't think with the condition of the motor and the weight of the car it was that crazy to get 20MPG's. When I first got the car I was getting 13-15 because the computer was bad and the motor needed a good clean and tune up. What did surprise me a little was even after the Trick Flow manifold it didn't really go down at all. I'm curious to see how much it goes down if and when I put Trick Flow or AFR heads in though........ any thoughts or experience?
