with the price of gas rising everyday I have been thinking about taking off my cai and returning the car to that factory tune file. so I no longer have to use the premium gas and can just run it on regular. If i want to. do any of you other guys feel this way or am I that only one?

 

[hotshot]

can't you just run an 87 octane tune with your CAI still installed? thats what i was planning on doing when i eventually get a CAI/tune myself

With a K&N CAI and a 87 octane performance tune my wifes V6 gets better gas mileage than stock.:bigthumbsup

 

[DJ86gt]

Yeah why are you running premium with just a CAI

 

[xchris]

premium with a cai actually does give you some gains but yea just get an 87 octane tune, i got 29 mpg with my CAI

 

[DJ86gt]

Damn if I had to run premium in my 5.0 but I got 29 MPG I wouldnt complain lol I would pay the extra. But I get about 19 highway Like 14 city

 

[Jshem746]

U can get an 87 tune.....

 

[cojakc]

i jus switched to 87 with my CAI as well. i miss the 91 performance tho =[ lol

 

[Black05Pony]

I'm about to switch mine back to an 87 tune as well... Cant decide though as its not my daily driver so gas isn't too big of a deal.

 

[jjjferro]

I travel about 400 miles a week at 22mpg. Lets round it to 20 gal of gas a week. Difference between 87 and 93 oct is about 30 cents.
So my answer would be no, for $6 more a week in gas I'll keep my added hp. :gringreen

 

[Redroostrz]

how much hp gains could i expect to see with CAI and an 87 tune?
also, what happens if i get a 87 tune an pump 83

You should see around 20 rwhp or so. If you fill it with lower octane you'd risk detonation. I don't think you can get lower than 87 though.

i miss my performance of the 93 octane tune.. it is soo noticable from the 87 tune that ive been using for some time now.. all my friends are convinced 87 on my car is SOO BAD for it. they say my car wont hold up down the road b/c 87 octane is soo "Dirty" lol but 87 still has some balls to it

 

[Salvatorey]

I'd just bite the bullet and stick with 93...Per fillup, you're talking less then a few bucks..

 

[travelers]

Yes you can run you CAI with a 87 tune. thats the best way to go.

i could have sworn i seen 83oct before :headscratch:
well idc about gas prices they have always seemed expensive to me haha.. so if i get a 91oct tune i could expect to see 35+ rwhp ?

No you're never going to see more than 25 even on the highest octane.

 

[Redroostrz]

No you're never going to see more than 25 even on the highest octane.

i see....:scratchchin k cool.

i got the c&l with the 87 tune and commute on a congested highway everyday and still see a solid 23 mpg.
