I'm in AZ with FBO running stage 2, 91 octane 5.7 and it has been great as far as driving. Any reason I should change to ACN and will it have less power or just not as harsh on the car? I use shell 91 octane.

All tunes are specific to the gas available to the owners. ACN map is just another offering for our gas to get the most reliable and safe power for the gas available. Check my ACN forum thread and you'll see what I mean |

All the research I've done indicates that ACN91 is still 91 octane, and that the difference is there are more detergents in ACN91 than other USA 91. Detergents to me mean something that will break down the oil as it lubricates the cylinder walls. So my inclination is to believe the ACN91 tune has a little less boost and/or timing than the regular 91 tunes, to prevent excess heat on the engine oil which is slowly degrading due to the fuel detergents.

Halim, if I want to get in touch with you should I email Protuningfreaks or something else? Since I just created an account I can't message you first on the forum. Thanks in advance!

I just realized what ACN is after reading this thread and looks like Im supposed to use that tune given I'm in Vegas.
I flashed my car with stage 1 91 fairly recently and it feels fine to me. The interesting thing is the ACN 91 shows that it is BETA. Anyone switched from regular to ACN that can share their experiences? |
