Custom Vs Preloaded SCT tune files?

Hello,

I was just curious if anyone could enlighten me on the differences between SCTs preloaded tunes and these custom tunes everyone talks about. I have been running the SCT livewire with the performance preloaded tune, aggressive tow/haul and firmer shift points. I have no complaints and the truck runs great with it, I get better mileage, the truck flys, and no engine trouble to speak of. Everyone seems to love their custom files from Innovative or Elite or where ever they come from. I noticed that the livewire has quite a few selectable user options right from the tuner menus. Has anyone run both the preloaded and custom and noticed any difference? Im just curious. Thanks!
:confused:

I just got to play with my SCT tonight with the canned performance tune. Its definitely pretty sweet compared to stock. I only have maybe 50 miles tonight of playing with it. Had a couple of scary points it seemed of over reving or something I dunno, but I am sending Eric an email tonight to get some of his tunes, if anything a more mild street tune with his trans tuning and such.

Hopefully I can get them sometime during next week, and if your around we could compare them on my truck or something.

I would deffinately be interested in seeing what the difference is. I am not exactly sure how they are writing these files but with everyone in a hurry to get them they must be good.

The canned tunes seem to react differently on various strategies. I've seen guys run in the high 13s with the performance tune and others that were nearly a full second slower. Some strategies are a little tougher to tune properly. You certainly won't be disappointed in Eric's tuning!

Yea I'm guessing by now he doesn't have to custom write the tunes anymore. I am just thinking he has a couple billion tunes saved that fit most all strategies and mods. Then of course he can totally custom tune it for your mods and likes, like a Race file with fuel pulled out for some 190cc sticks and a stock turbo or something. Or a file for a fixed geometry turbo and 150cc sticks or something, but I am sure by now he has seen most all the combinations for each strategy out there.

Yep, big difference in Innovative's tune vs. a canned tune. Although I will say I wa pretty surprised at how well the SCT canned tunes performed on my truck too.

We are installing one and some gauges on a buddy's 06 saturday. He is going to run the can tunes for a little bit then go with some custom tunes. I keep telling him just the can tune is going to be a BIG diff from the banks he got rid of.

The canned tune on the SCT will be a big difference from the Banks from what I've seen at the track.
