My car ran well with the out of the box SCT 2 tune. When I installed my 100 shot of nitrous I had AM send me a 100 shot tune. I'm not really liking the tune when the nitrous isnt being used. The idle is rougher...seems like a slight miss. Can I go back to the stock tune but still change the axle ratio and tire size while in the stock tune setting? I'm gonna look at my plugs too.....it was just running really shitty today. Can I get a better tune emailed to me from somewhere? I just want something decent before I get a dynotune.

 

More Power Tuning does a better tune, but just get it dyno-tuned....save yourself trouble.

 

You don't have to drive around on the nitrous tune all the time. If its really that bad of a tune ask AM to send you another one because yours sucks.

 

If you're up to spending another $50, you can get one from vmptuning. Theirs are great.

 

I would NEVER run Nitrous on a mail order tune.You need to have it Dynoed before you mess something up.
