Up until recently I had my EZ set on level 3 and it worked well.
BUT on my pursuit for more power
I decided to bump it to level 4. The truck has great low end (take off) 5-35 mph, but doesn't seem to pull as hard (35+) after it gets going. I am not sure if it is me or if there is a actual difference, but there definately feels like there is a loss (like the truck is running out of fuel or something). This is running WOT with no load...
I have changed the Fuel filter and there was no difference. The truck is a 04' ho, 48RE, with 8,XXX miles on it. everything else is stock. I have also put in some fuel additive / lubricants, but nothing changed.
Also for reference, I have never installed the elbow...
Are the torque curves on the box different with settings, or just bumped up a little (but the same curve)??? I am concerned that I am dropping the fuel pressure (just thought) but don't have a FP gauge to verify that.
Any ideas???
thanks
Dave
