I know about all the questions in the world have been asked about delivery valves.

im torn between DDP DV's ($260) and just getting mine machined out to full cut's ($50)

Obviously both will flow too much fuel for the stock turbo, i got it. A turbo is in the plans...

I'm wondering if there is any fuel economy gains or losses to be had between 131, 181, 191, ddp's or full cuts? (i suppose .022's and laser cuts also haha)

on another forum I talked to a guy (with a 1994 dodge almost exact mod's as mine) that claimed 4mpg increase when he went from 131's to 191's

full cuts=laser cuts
which also=poo on the street IMO

There should be no mpg gain going to a larger set (it removes less fuel each injection cycle%

I can also get some full cut delivery valves cheap. But are they really that bad on the street??
