Im on the 140 tune. I know DP said they can't do as good with the SCT as a true chip, so I would assume the same with Elite. I'm getting over 25lbs with the boost fooler, so I wouldn't think I have a leak. My truck feels like it has no top end, but I haven't noticed signs of the TC slipping, and am assuming (and was told by Elite) that I'm not able to supply the fuel for the tune (stock HPOP and Injectors). But I wouldn't think that would hinder me to the level of a cherokee.
