2007 Mustang V6 knocking when accelerating


Hey all, this is my first post. I have a 2007 Mustang V6 manual with 24k miles. I recently installed a BBK CAI. Since installing it, I get serious pre-ignition (knocking) when accelerating in 3rd & 4th gear. The reason I went with the BBK, is that all of the forums that I have read including BBK's documentation is that it did not require a tune. I have not gotten any CEL or codes, but I am concerned for long term damage. Should I be? I called BBK support and they suggested that I move to a higher octane fuel, but according to the Ford docs, the 05 - 08 Mustang is rated specifically at 87 octane and states that going higher could cause damage.

Any thoughts or suggestions would be greatly appreciated.

first move to a higher octane fuel and see if this solves the knock. to verify that it is in fact a spark knock because of fuel starvation.

Thanks for the help guys. I will definately do so. Which tune is best for the V6 in your opinions? Are they mod newby compatible such as myself or should I just go have it professionally done? I am pretty savy when it comes to general auto mechanics, but do not like the idea personally of blowing up my engine.

SCT tuner is the best option currently for your year of mustang. id recommend sniper because there package is by far superior but they are still developing the strategies for the 07 mustangs. should be a few more weeks yet.

a custom tune would be best.

I would invest in a hand held tuner like the one in my or jugs sig.
be sure to check what your local dyno tuner uses before making your purchase though.

a do it yourself tuner will be fine. The brands everyone seems to like are SCT, Sniper, and Diablosport. one of those will work fine for you.

Thanks guys. You've both been a big help.. Also BTW Jugs, nice review of the Sniper. I just read it. It looks easy. Do you know if the flash file has a time/date stamp or date identifier on it? If I get it tuned and revert back to the factory tune for warranty work, will the dealer be able to determine that it was tuned at some point and time?

the flash files do have a time/date stamp as well as me and another sniper patron have been tinkering and he has developed a nice little proggy to document your tunes, the settings and the results automatically. but thats all ill say until he is closer to a release candidate and i see if he wants to release it as freeware/shareware. however i am beta testing it and its working great

forgot to mention no the dealer wont know if you flash it back to stock before warrenty work

be SURE to mention to the dealer not to re flash your ecu while getting work done
if you change your ecu's tune in the slightest your screwed for the most part because your tuner won't recognize the stock ecu and therefore won't tune your car.
