I think that's what the tuners do. So it's a good idea.

The power delivery is also much smoother when I get on the gas. As far as shifting goes, it definitely seems smoother. Weird, but yes it worked.

I will say that my car sounds a little tamer though (very little). Perhaps cause it was running rough before? BTW I have the CA inductions intake and Flowmaster AMT installed way before the pull.

Good to hear. Give the meter time to give you a truer gauge. My mileage went DOWN for an average but up a bit when measured. Mainly because the excitment had me stabbing it.

I cant get rubber in fourth anymore. The car does idle smoother and still pulls really hard, and I actually get a tad more rubber in 1st and 2nd than before....?? Car is bone stock. Not completely complaining, would like to get rubber in 4th again though. I was doing a lot of bragging. Thoughts? I've tried in all the trans modes btw. And for you LS3 guys, what modes do you use when? Mine is a daily driver, but I like to be ready..

I just didn't want anyone here getting the idea that 30+% gains in mileage are yours for a fuse pull.

Agreed.

As long as you know you have 91+ octane in your tank, go ahead and do the fuse pull one night..
My dealer put 87 in upon delivery, against my request. So I knew I had to do it...

1JEWLDSSRS · 08-16-2011, 06:33 PM

Same here, if the car seems a little sluggish, they filled mine up with 87, and the only way I caught it quickly was when I started it up once when the engine was hot, I heard the "spark knock" and I knew it had 87 fuel in it and heard it, ran the tank down, filled back up with 93, went home and parked the car for the night, pulled the fuses, re-installed in the morning, and what a different car. Good luck..

i can only get 91 where i live. should i get a full tank of 91 and use a octane booster before i pull the fuses?

You should be fine with 91. No octane booster required.

I have a question. I am about to get my car dyno tuned after the turbo is installed. When I got my car, the dealer put lower octane in my LS3. Ever since then, I've put higher octane in though. So, I would assume I don't need to perform the fuse pull if I am getting a dyno tune anyway, correct? I would assume the tuner will adjust for the computer for higher octane.

Correct sir. The tune will take care of everything you lucky bastard.

I would do the fuse pull BEFORE going to the dyno. It will save you and the dyno operator time dicking around with what should be right in the first place.

Not really. He's gonna copy the high table over the low one anyway. But it can't hurt.

Will every tuner do that? I just was trying not to assume anything.
Sorry if I'm putting out bad info, that was not my intention.

Rhino79 · 08-16-2011, 10:54 PM

Not every tuner will copy the high to the low, some use some other methods. Some don't do anything different to the low or the scaler tables. I will just copy and paste, if I get bad fuel, I have efilive, I ll throw the stocker back in. I just don't want any chance of going to run and it finding itself in the low octane and be that down on power.

Anyone know if it made a difference on how long they left the fuses out.. ex 30min, 2 hours, 8 hours...?

You just have to wait long enough for the ECM to bleed off any voltage. Half an hour is probably fine, but if you can do it and leave it overnight you won't have any questions.
