Was your tank completely empty of 87, or is the tank a 91/87 mix? Before I put my JLT2 and upload my Bamatune I ran nearly dry my 87 tank, then threw in half a tank of 91 and am running this nearly dry just to be on the safe side.
If I were you, I'd try reloading the tune and trying again, if that doesn't work switch down to an 87 tune until you are finished with this tank of gas.

Depends on how senstive the tune is I guess. You have nothing to lose reloading the tune, if that doesn't work, I'd just give the guy who you got the tune from a call and relay the situation.

can't go out for another test drive because the wife went to airport and kids are sleeping.
Car is idling funny and smells very rich, the garage is full of fumes.

Well, my 2cents.
I did not unhook my battery, but I did run it almost dry with the 87 I had in it and then filled it up with 93, ran it to 1/2 tank and then refilled again. No problems. Jay at JLT says that going to a higher tune, the mixture of the fuel octane is important.
Go back to the 87 tune. First unplug the battery, then retune and tell us whats up.

It's probably not your gas. When I installed my JLT/SCT2 combo we immediately dynoed it with 87 octane in the tank. Unfortunately my tuner had mistakenly loaded the 93 tune. We made one pull before realizing the error. We datalogged and got no evidence of pinging from the many knock sensors. After swapping the 87 for 93 we made another series of pulls and I ended up making only 1 HP more using higher octane with the same tune. Don't know why. Whatever, it runs great - on 93 of course.
I would make sure the MAF sensor is seated properly. If that isn't it maybe Jay can help.

check all your connections to the CAI - after I installed my TBS, I FORGOT to clip back in one of the three black plastic electrical clips (MAF being one). The car started - immediately went into safe mode, then died on me. I was about to panic, popped the hood to take a look, and went DUH.
Car was fine after that. Just unhook them all and reclip in and see.....
