Unhappy CAI and Bama tune.. Disappointed so far

So I put in my CAI and dropped the 89 octane base tune on. Feels much slower then it did stock. Seems like it loads up or something. Thought it was going to die coming out of the driveway. Not sure if I want to go up to the 91 (mid) tune or not. I put a full tank of 91 when I filled up last.

What do you think? Change the tune and try again or not risk it and call Bama in the morning?


Update:
Just wanted to update everyone in case you don't want to read the whole thread. Issue has been resolved. Thanks to both Chris's at AM for pointing out the Venturi Tube is not needed with the Airaid intake and bama tune. Hopefully instructions will be provided for all new kits to point this out.

It is probably just going to take some time for the computer to relearn the throttle... Drive about 100 or so miles and it should be fine.

That doesn't sound right at all. Maybe try returning it to stock and reloading the Bama tune again...

Call bama. You might need to run a data log but something doesn't sound right at all.

Is the opened end of the MAF sensor supposed to go towards the airbox or the TB? I put it towards the airbox. Looks like it can go either way.

you filled up with 91 octange gasoline, you tuned your ecu to run 89 tune. thus changing making your ecu think its on 89....but its on 91.....follow? PUT THE 91 TUNE ON. a tune changes the timing and other stuff to run that spec of gas.... you arent running the correct gas for that tune.

I'll disagree with you and leave it at that.

how are you disagreeing with me? you put a tune on your car to run 89 octane gas. but you dont have 89 octane gas in your car, you have 91... how can you argue that?

I don't think I am arguing. Do you know how octane works?

On my 2010 GT, I had the CAI/Tuner from AM and it did not work for me. I kept on telling myself it was better but in the end, it seemed to me it was no better than stock. I tried all 3 tunes with the octane accordingly. Then you have to deal with properly oiling (when its time to clean it) the filter or the car will die frequently. I will never do a CAI/Tuner again. Just my .02 cents.

Who knows, maybe mine was off as well.

I instead got rid of the 2010 for a 2012 and man is there a difference!!!!!!!!!!!!!

Good luck

The ecu will adjust parameters up but not down. Fine to run a 89 octane tune with 91 in the tank. Not good to run 91 tune with 87 octane though.

He can disagree because:

91 gas with 89 tune = A OKAY!!!

87 gas with 91 tune = NOT GOOD!!!


You can ABSOLUTELY run a higher octane gas than the tune requires. It will not cause damage and only be a waste of money (since higher octane is more expensive). The car doesn't know or care what octane you have. The higher octane prevents detonation that might occur at a lower octane. That allows the tune to be a a little more aggressive in the timing and such.

Under the hood. Haven't put all the trim back on. Was going to do my Boss intake this weekend but now I may hold off.

see, from my understandin with the tunes was that it didnt allow for the ecu to readjust itself for the different octanes. thus why there are different octane tunes?
i will say that i am wrong, my bad!
