Unhappy Going Stock

Hate to say it but I have to go stock. I made another appointment to try and get the shake, miss, studder out of my truck. When I made the appointment I talked to the tech that should be doing the work, and he wanted me to go back to stock and drive for a couple of days so it could reset all the ready codes. Is this really needed? I was just going to do it the morning before I took it to them. But I do want to make it as easy as possible for them to fix it, I'm tired of having this porblem that the local dealers can't pin point.

Any input would be great thanks.

I hate going stock When I bought my SCT and guages the SCT came first and I couldn't wait to try it out. So after I installed my guages I went stock just see the numbers. I was trying to talk a friend to "FIXING" his truck. He took mine for a spin durning lunch and was im more shock that I was.

You're lucky to have a dealer that doesn't care about the tuner. The one I have to go to complains about an exhaust.

The computers they use to diagnose the truck assume stock PCM parameters. Having aftermarket programming on there when they try to diagnose could cause all kinds of problems. I don't know why the emissions readiness tests being complete would really make any difference, but for the previous reason alone, I'd put it back to stock.

I've heard something along the line as that, but do I have to drive around for a couple of days? Stock suck. EGT's are all around higher, not to mention the massive power loss.

FYI I'm out of warrenty And the tech's at my local dealers could care less after that, a couple even thought I made the right move as to getting SCT.

The tech wants to see if your truck will throw codes in stock mode. Doesn't really make much difference if you're not in warranty anyway. Reflashing to stock and driving for a few days will give the truck a chance to throw the codes, but IMHO I'd rather have it read before you reflash it to stock, just in case it's a crapped out injector. Have you tried reading it with the SCT (which is basically worthless for a DTC reader anyway)?

I've never had codes pre/post SCT. But I did just take alittle drive stock.


Keep in mind this was about 1 1/2 hours arter getting home from work so she is still mostly warm.

Pull out of the hood. Frist accelleration to 50 mph got lots of turbo bark at about 45 mph, went away quickly then a big lag in power. I held peddel the same, came back to normal held 50 came to a stop. Second accelleration to 50 mph same thing. Thirid acceleration to 60 mph same thing with a little less power loss. Drove to get some Jack a couple miles away parked.

Jumped back in drove home the same route, drove like a stock PSD. Minor shacking, surging as always.
