Jus got thru putting my turbo-back exhaust on the LMM and with the Quadzilla on the 110 hp this thing is awesome to drive! Have had no problems with the DPF being removed and on a long trip with it this morning I averaged exactly 19.0 MPG with 33's on 20's. I am very pleased!!! That MPG calculation was by the DIC. Haven't filled up yet to do any real calculations.

Glad to here it, keep us posted. I’m getting ready to do the same thing.

Which exhaust did you go for........are you blowin' smoke on the 110?

Your DIC is no where near accurate with the Quadzilla loaded...The DIC is thrown off by any programmer. With My PPE on 225 my DIC says over 20 MPG and if hand calculated its more like 16 MPG.

YES! This thing blows smoke pretty good with ULSD but it really blows some smoke with LSD. I can use that now that i have no kitty or DPF to clog up...hehe! Truck really runs great!!!!

How many other guys have noticed this??

I have an '03 Suburban and my '08 LMM, and both of the DIC's are VERY accurate with MPG's.

I just ordered my Stealth2 and would be bummed if I can't rely on the DIC for MPG anymore

I have been running the Stealth on all different settings and find the DIC accurate at all times?

It's just taking information from fuel flow and mph, so I don't see how a programmer could mess it up. Not my department, though.

Because in the programming when the ECM calculates MPG for the DIC it uses the fuel volume desired in MM^3 to calculate it. Now when a programmer is thrown in it adds more fuel by increasing pulsewidth (usally) and the ECM doesn't recalculate for the new PW. Example 20MM^3 @80MPA=1321microseconds of PW....Now a programmer might modify the PW to be 1600microseconds in that same cell, but the ECM still thinks that it is getting 20MM^3 of fuel when it's really getting over 40MM^3......

Ive Been Running Mine On The +70 Tune With Dpf, 19.5's W/ Heavy Azz 14 Ply 33's And I Have Been Getting 16-18mpg Hiway And 13-14 Around Town And It Seem Faairly Acurate........way Better Than Stock........
