what do you mean by clearing o2 sensors?

thanks!

I just ran the tank down to 12 miles left (according to the computer) and then filled up with 93. I drove home and loaded the 93 tune on... you won't hurt the car by running an octane higher than what you're tuned for. But you certainly don't want to run a lower octane than what you're tuned for!

I meant I cleared the CEL codes, not the sensors... sorry! :-)

so where do you guys get the 93 octane fuel? Gas stations usually have 87, 89 and 91 octane fuel or am I wrong?

As far as next mods, I'm strongly considering getting NSR cams... but 3.73s are also a definite maybe.

I don't want an o/r h or x just because of emissions... we need to pass them in Woodlands. Do you 'have a guy' that will hook you up with a sticker or something?

Also, I'm gonna try to get a pass on Friday night to head up to Conn's with my buddies. One has an 05 w/Paxton Novi and the other has an 07 w/Hellion turbo... if so I'll shoot you a PM so we can try to meet up.

Yeah that would be cool. Just hit me up if you do . I would lovvvve to get cammed that sound is amazing

You don't live in Texas do you...

In Texas there is 93 at almost every single gas station around!

I think it depends on what area you are from....I can get 93 oct at about half the stations in my area. But if I was going to take a trip, I would drop my tune down to the 87 or 89 (or take my tuner with me). I don't know why some areas don't have 93 oct - state laws? higher taxes? sucky distributors?

States with higher elevation usually have 91 octane as their max "premium" rating, while states closer to sea level usually have 93 octane as their max "premium" rating, and it can be the exact same gas. This is due to changes in atmospheric pressure.

I live in South California and it is pretty hard to find 93 here.
Does Brenspeed offer a tune for 91?

Yes, I'm sure they do....If my memory is correct, their standard "three pack" consisted of a 87, 91, & 93 tune. I changed the 91 to a 89 (same price).
