Does removing V4 hinder mileage THAT much?

[TahoeTruk]

Thinking of removing with either the range plug-in or a custom tune. And anyone want to chime in as to how much it actually worsens your mileage? Is it really that bad or is it worth it thanks

Would really like to know this myself.

Some people say they noticed a 1mpg drop. You honestly won't be able to see a difference though

Very slightly if at all, but since they use less oil, you're money ahead without it.

I noticed absolutely zero difference when I removed the V4 junk from mine. It's well worth it to remove the worthless "technology" IMO in the gmt900 it does nothing

Get a GOOD tune along with eliminating the D.O.D there will be no loss in fuel mileage. Also the GMT900 will be easier to drive.

Awesome thx guys. I'm doing a black bear tune next week. So psyched about it.

I eliminated mine when I did all this and still get 18.5 in the city and usually 21-22 on the freeway same as with the DOD

K&N cold air, American Racing headers and y pipe, Corsa Sport exhaust,Comp Cams cam which Ill have to post specs later,Comp Cams 29618 springs, rocker trunnion upgrade and 7.4 hardened pushrods, GM LS7 lifters and LS2 timing set, ARP headbolts, all GM gaskets and with a tune it made 340 to the rear tires. I think stock its like 250 or something at the tires.
