I'm not really sure. Contact 06monteSS (Lew).

Well I installed the 91 Octane DOD tune, and I can definitely tell the difference in acceleration. It's much quicker up top through the power band. I know it can't, but it does seem to down shift quicker, maybe it's just the added grunt up top that makes it seem that way. The 4 to 8 cylinder surge that you experience is kind of annoying though. I drove from Northwest Indiana to the north side of Chicago (O'Hare) on Saturday and when I got home I was around 22 MPG. I don't think that's too bad after spirited driving and going through Chicago traffic.

I'll be sure to make note of the DIC readings on my tanks to follow when I'm doing my normal weekly around town driving.

I'm very happy with my decision though and I'll probably get a custom DiabLEW tune eventually.

 

thanks rick! looking forward to seeing what numbers you come up with in the near future and how much of a difference the diablew tune helps also

edit: diablo doesnt support 2007 monte carlos

 

Will the Diablo tune work on the 3.5L?

 

nope. . . it's only a v8 thing. . . and only the 06 monte's at that

 

No but an Overkill tuned would.

Thanks guys

 

i have the 06LT,,i 1st wanted the diablo since its handheld, but opted for the HPtuner by a shop near me,the difference is incredible, and now hes called me up after a few years to tell me theres an update on my program where he can access the transmission now, order new cooling lines and waiting on a day he can do it,,original tune was 550$,,200$ alone just to access my pcm, but it is worth it,,my main tune is shorter shifts,better air to fuel, and no more rev limiter,,other smaller details to which i forgot wen i go back i`ll ask for a printout. i did not gain any horsepower but got more torque,with the new tune he expects close to 350lbs tq with and upbeat of hp from 211 to 250 max if i keep it at premium fuel.
,,,i know this is not on topic but a friend veered me to a site for the SS spoiler for 06-07 models, is this trustworthy? i followed other topics and everyone warned against similar models,,just asking cause i would love to ditch my nerfboard
