I was going to jack the front of My Moms' Cadillac and set the cruise for a while and watch that mileage climb . Her bone stock DHS Northstar is only getting 15 and like 22 to 24 highway ,,,,,,Yay .

I the best mpg I've gotten city driving is 12.6 with the LS6, 236/242 114 LSA, long tubes ory and a few other mods. I have the STRONG gas smell as well but I have always thought the bad mpg and gas smell was bc of the cam and ORY just like you stated for your car... I have been wanting to get another tune to see if I can clean it up a little, but haven't as of yet.
