well my superchips came in today ,and all i can say is absolutly amazing, filled my truck up with 91 octane, then updated my superchips, pluged her in set it 91 octain performance , took no more than 10 minutes to do. started it up, it idles alot better, and put it on the road 1st thing i noticed i barly touch the gas to make it go , before i would have to go half way down if not more on the pedel, to get this little touch it has now. i can feel it threwout the whole rpm. when i used to do a brake torque it would take some seconds to spin, now its just an instant spin. i think it was a good buy for 400 bux. and its always updateable. and i asked superchips why a such a big gain !!!!! http://www.flashpaq.com/forum/viewto...9b863f7e4bb58c

 

Glad you liked it.

I wonder if they've done some more work on those since the old 3715 unit. I know the old unit was not upgradeable, the newer is via the internet. I had an old unit and the SCT blew that away hands down. I do have the 5.2L engine, so perhaps it would not be that much of a change from what I experienced before. I wonder if anybody has the old advertised gains and could compare to the newer model?

 

I am also interested. The SCT up until the Flashpaq 3815 model was top, and maybe still is, but if the Flashpaq can get very close to the same results, and you can clear codes and what not with it, I think I'd want the Flashpaq.

Great, another tough decision to make.

 

You can currently clear codes with the SCT tuner. Superchips does the tire/speedo calibration, not sure why the SCT can't do that.
Superchips isn't going to rewrite you a custom flash though. You're getting a canned tune, and canned for a bone stock truck, mind you. If you have any desire to further mod your truck, the SCT is the way to go IMO.

Or you could just take Neon's advice when he buys his SCT. He did just return the superchips after fussing with it for an hour.

 

SCT is supposed to have the tire/speedo thing within about a month, I'm told, but tune for firming up the tranny shifts is still a ways off. I'm not talking about shift points, but rather getting rid of the stock PCM's programming building in some tranny slippage to make it smoother for the soccer mom crowd. To me, that's a big feature the SC offers, it snaps into gears, which, on paper anyway, should also extend the life of the tranny.

I almost agree with you 100% about who should go with an SC and who should go with an SCT. Stock trucks, I'm with you, but the standard cat-back, CAI (or drop-in) crowd I think would be fine with the SC. But you start getting where I'm at now, (LT headers) and where I'm going (KRC 210 Cam, with -4 degree custom grind for way more low end torque) and you are well beyond the capabilities of a "canned tune" helping you...

lastrights: I'm glad the 'ole butt dyno is registering big gains with the SC. It's more indicative of what other people on some other forums I'm on are reporting with the 3815 now that it supports your 5.9. I don't know why the young man who returned it didn't see much out of it, but he seems to without a doubt be in the minority from what I'm hearing...

 

See, now I'm curious about this...

Isn't getting your cam ground 4 degrees off centered basically the same thing as setting your timing chain 4* advanced or retarded? The chain times the crank with the cam right? So offsetting the chain is basically the same as a custom ground cam, or am I off on something here?

The reason I ask is because I've heard of guys advancing their timing chain set via the optional keyways, but I've heard that the PCM ends up compensating for most of it and that it doesn't work quite the same as it used to on older style engines, kind of like turning the distributor doesn't work like it used to.

I'm sure I'm probably missing something in there, I just don't know what.

 

Now, I am not very knowledgeable in engine internals, I'm more comfortable talking suspension & lifts, but I bowed to the expertise of my local performance shop on this one. They recommended my e-fan, which I would never have thought to get and a local coating shop to ceramic coat my headers, which came out far better than any factory coat I've seen. The great thing about this place is I can go and ask questions, and they know on the easy stuff like the e-fan and header install, I'll be tackling the installs myself, and they'll still take the time to talk to me about them. BTW - I'm not even gonna try the cam, it's out of my league.
But I would imagine if I got the standard grind of this cam I'd get all the power making benefits (lift, duration, etc.) of the cam and you could install it offsetting the chain for the timing aspect. This was not discussed, but the next time I stop in I'll ask about any pros or cons of doing it that way.
As for the PCM, I'm sure that's one of the reasons I'll need to go with the SCT and a couple of custom tunes for this setup.
Originally it was quoted to me using my existing Superchips and a separate piggyback, but since then I've had to push back the project as I'm hardly working due to family health issues. Now the SCT has come out for the Hemi and using it in place of the Superchips would allow a custom tune or tunes to be written to tame that cam, no need for a piggyback. We've discussed a 93 Octane Performance Tune, a Towing Tune which will produce even more low end, but at the sacrifice of some high end, and possibly a max mpg tune, still for high octane fuel but a tune that would maximize fuel economy possibly for daily driving or long trips.
Financially, I'm not ready for it yet, I've been close, but things keep coming up, so maybe by the time I've got my ducks in a row, the SCT will have the few features I like in the Superchips that it currently lacks...

 

lastrights, did you have to update it before it would work on the 5.9? this is what i have been wanting to here. i will be getting one shortly. i am glad that you were satisfied.it always sucks when you spend that kind of money and arent.

 

yeah takes no time at all, just make sure you read directions, and make sure you let it read your stock files 1st so you can always set it back, you wont be dissipointed with it!! still playing with it, i didnt try the towing tune yet, prob wont either because i dont tow, its pretty much a show and have fun truck. but if i do tow i will be sure to use it.

 

So you have to run premium fuel to get performance out of it?
will your mpg increase? is here a 87 octane tune that will give better performance than stock?
