well no shit that 100oct is better gas!! but for just a 2.7? dont bother unless you have the means to tune your car and take advantage of the increased spark timing that high octane fuels will allow.

A perminant tune for 100 octane is a bad idea unless it's a track car only. Otherwise if you end up putting anything less... bye bye LSJ. If you have the means to ONLY run a high octane tune when you have the fuel in the tank, then go for it. But unless you personanly have HPT, I'd stay away from a high octane tune like that.. IMHO

does anyone make chips/ flashs that can put multiple tunes on for this car? i know on my GT i have 2 tunes one fore 87 one for 93. i can just turn the car off, flip the switch and start her back up and the timing is bumped out.

Pretty much just HP Tuners for now... the Mustangs and Fbodys have ALOT of that type of stuff...
