COcycler, thanks. I am impressed with your pump-duese fuel economy! I'm guessing you are a patient driver. You've got some nice mods, too.

Arragonis, the full intake mod definitely helped power a bit. Not much, mind you, as my ALH engine came with the little VNT15 turbo and 90 HP rating. Fuel economy improvement was not measurable (had a lot of other changes going on at the same time though), but there's no way reducing intake restriction on a turbo diesel is going to hurt! The only parts of the intake tract that is from a V6 are the mass airflow sensor housing and upper airbox lid though.
