Everyone complains about mpg in the winter and my PPE on lvl2 gives me the best mpg. I started messing around with the custom changes. I turned off the defuel and took the fuel out of all the tunes. I left the rpm increase in and the timing in. Level 2 felt a lot different than the normal 2 obviously. Better shifts and no power. So... in went level 4, 225 hp on mtr, with no fuel added and no defuel??? No idea what it lays down now... Better power and boost still hits around 28 psi according to the insight. At full throttle all the shifts are firm. Before, wot on the 160 tune with no changes, 5th and 6th gears would slip the tq. Now on level 4 flat footed its fine, no tq slip, obviously there is no fuel added and less hp. EGTs are waaaay lower also. Barely hit 1100* on lvl4... makes sense because of more boost and no fuel increase. Usually can hit 1700* fairly easy when rail psi drops.
I would almost tow on lvl 4 with those changes. Also fuel pressure stayed where it should and never dropped like on the standard lvl 4 tune.
This is what I have seen and understand so far....My questions now are...With these setups will I get better mpg than the standard fueled tunes? Is it better for the motor with just timing and boost added. How much HP is added with no fuel if any just from boost or timing? Finally is it safe to tow on lvl4 with no fuel added? Would lvl 1 with standard tuning put down more power than lvl 4 with no fuel. EGTs are lower on defueled 4 than standard 1 tune.
Sorry for the long post...got the wheels turning in my head tonight What do ya'll think haha!
