Any Problems W/ SCT Tune?

I just got my SCT Tune a couple days ago and I've had some problems.

- Rough Idle

- Surging around 2000 - 2500 rpm, especially noticable when cruising in 6th

- Check engine light

Has anybody else here had those problems? If so, was your supplier able to correct them?

Thanks guys!

It doesnt matter what tuning software your going to use, issues like that come from the tuner rather then the software *sct, diablo...autologic...*
If you have an SCT shelf tune that might happen but who knows....
Take it up with your tuner....

And Tom, flame on!!!

i actually have those issues right now, it's been worked on, but i'm gonna get my check engine light read tomorrow because today is a holiday and everywhere is closed. i have the rough idle at like 1500-1750rpms, abut it's not as bad as before.... but we'll see what the CEL says and i'll tell my tuner from there on, and i'm sure he will work something out... =)

Mines great, never had a single issue. I can data log, read codes, clear codes, and stream live data to a laptop but I guess thats what you get when you pay the extra money for the better hardware and tune. Anyone want to guess which one I settled for? I know I'm going to start a shit storm here but when your talking about messing with your ecu I always said you should buy the best and to hell with it costing a little extra. Just my opinion. Let the dirty replies begin.

My car has never run better. A fellow svt owner rode in mine last week and said mine pulls better than his, and he's got the orp, k&n shorty and borla. Did you follow the instructions to the letter when loading it? Is it Hypnotics tune? Wayne will make it right if it's his. Are you going fast enough in 6th, and it still stumbles? A little more info please.

If you get the sct excalibrator, and you have tuning problems, you can just set it back to stock until you figure it out right?

hey, everyone.... with regards to the power of the tune, yea i got plenty and it's awsome... i love the power level, also i know of someone that has tom's tune that end up getting a CEL from it, but you know what....sometimes it's just little problems that cause the CEL to come up, it's no biggie, anyways yes i got it from Hypnotic, and i'm gonna get the code read today. also when i'm in 6th and at part throttle at very low rpms say 1250rpms and as it moves up slowly it will studder/surge, but if i press the accelerator pedal more and it accelerates pass that zone quickly than no probs at all, but i'm usually in that zone in 2nd gear when in traffic so it's kinda hard to stay outta that zone, also i don't want to be shifting into first while i'm rolling. but hopefully Hypnotic will get it fixed soon. he's been the greatest help and so far many people's problems seem to be resolved but mine... :(

Yes, I'm making sure that I'm going fast enough in 6th. This is the same chugging that was happening with early stock tunes (pre-YRFO). Although, this chugging is more violent. Probably just a quirk with my car. The tune just probably need to be tweaked.

I'm not too worried, I'm sure everything will get worked out. The customer service so far has been simply outstanding.

I had the same problem with the Beta Tune from Focus Sport. But the new final release eliminate all those surging around 2000 to 2500 rpm range.

CEL is b/c the tune is prob. running too rich. OS sensor is abit too touchy especially for 03 model.
