Mine did it at about 70mph. Flushing and changing the tranny fluid made huge difference on mine. Truck only has 35k on it.

What supercharger are you going with?

Bump...make an offer for the adapter,

Good to know. Thanks

What parameters do these trucks use to calculate the fuel economy they display? I am wondering if going to a larger injector would skew this #, even though I don't believe it is highly accurate.

Mine made over 460 whp, going lean up top with a custom tune and intake. Going back in today for bigger injectors.

I just put the 3 l Whipple on my 5.3 and couldn't be happier. I have to believe with labor, the cost is similar if not less to what you are looking at doing and the drivability hasn't changed a bit. I did heads, cam and intake on my Trailblazer SS and the cam caused drivability issues I did not like on a daily driver and made less HP on the LS2.

It definitely fixed mine, I was hoping maybe I could get them to flush and change the fluid. Either way, thanks for the info.

I just paid a local shop to do this, what are the odds I can get a refund from GM?

The engine coolant sensor is measuring engine entering coolant temp, which is the same as the leaving radiator temp.

I bought the bypass kit and it works great. I believe the external cooler is after the radiator.

I went with the 3.0l whipple and couldn't be happier. With a custom intake and tune it made 474 rwhp. It did run out of injectors up top so is going back to Cordes for LT1 injectors at the end of the month. Its my daily so it probably won't be getting any other mods, so they said those will be plenty
