I tried posting this in another thread but I did not get a response so I thought I would try a separate thread. Sorry if this has been covered before. I was unable to find anything that covered my question.
I have a question regarding the fuel used after putting in CAI and tuner. Is it possible to continue using 87 octane gas instead of higher grades? What is the affect if you only do the CAI without the tuner?
stlwagon gave you the correct short answer. I'll expand on it and be a little more verbose.
DON'T do the CAI without the tuner unless you have one of the restrictive types that don't require a tune (Demolet, K&N, etc). Like stlwagon said, you'll run lean otherwise. Most CAIs give you more power because the airflow (and fuel if tuned) is increased. More air requires more fuel to keep the mix ratio correct.
The answer for running 87 octane is yes, if you have the correct tune for your CAI. Bamachips makes a 87 octane performance tune for the JLT and C&L CAIs. You'll see some mild performance gains with the 87 tune and you won't have to worry about burning up your engine from running without one. Pretty sure Brenspeed and the other tune makers make 87 tunes too.
Naturally if you can afford 91 or higher octane fuel, you'll start seeing much more dramatic performance gains. At that point, the tuners can tune the engine with some timing changes which takes advantage of the higher octane fuel and gives you a lot more power and torque.
I'm running a 91 octane race tune and just can't bring myself to change to the 87 tune. I enjoy the extra power too much and would rather pay the extra in fuel than take the hit in performance.

Thanks... I was just too lazy to go into this much detail

I know you help out on all the different forums so your time is at a premium whereas I just cruise the S197 forums. Helps me having taken typing class back in highschool too.

Since I use the car for a daily driver I did not want to waste money on 93 octane gas while driving in stop and go traffic. That is the reason for my question about 87 octane gas. I want the benefit of more hp when I drive on the weekends though. What kind of performance increase do you think I will see if I do the CAI with an 87 octane tune.

I had my car dynoed when I had the K&N CAI and GT dual exhausts with 87 Bamachips tune. The results were 200 HP at the rear wheels.

Go for the CAI with tune and load the 87 octane tune provided. You'll notice the improvement in power and throttle response.
I think that is the way I am leaning. It doesn't look like a difficult job. I want to try and do this with my 15 year old son. I am also looking to replace the stock muffler. Any recommendations?

I think the common concensus for the best V6 muffler is between the Flowmaster A/T and the GT take off. The GT muffler is a good inexpensive muffler, but alas, I went with the Flowmaster because I wanted a little more oompf. I just received it today, and I'm going to put it on sometime this week, maybe tonight. I'm stoked, it's like Christmas.
