Help, please!

I have an SCT X3 that I have been running with ID's Aggressive Street tune. Well, I finally decided to drop $80 for the Extreme Street tune, but after I downloaded it and tried puting it in my truck, it won't start. Everything seemed normal when I was puting it on my truck, it even said download complete. But, it won't even turn over. I installed the Aggressive Street back in and it cranked right up and it runs great. Is there a step or something that I am missing? When switching from one tune to another do you have to go back to stock first? I just want to see if it is something I'm doing wrong that I can fix before I call SCT or email Eric. Any help and/or comments would be greatly appreciated. Thanks!

The Guys from SCT told me to always go back to stock first before loading another tune.

Yeah, that's what I'm thinking. I just haven't had time to try it. It's supposed to rain all day tomorrow so I probably won't be able to work and I can give it a try. Thanks for the reply! Anyone else?

Returned it back to stock today and drove it around awhile, then tried to put the Extreme Street tune in, but it did the same thing. I don't know what the problem is. I'm still sure it's something I'm doing wrong because I'm fairly new to this stuff and really don't know what I'm doing. I think I'm going to email Eric and see what he has to say.

I would email Eric and tell him what its doing....if its the tune he will fix you up.

Did you ever get this resolved? If so, how did you like the Extreme Street? Was it a big difference over Agg Street?

I'm willing to bet that the scaling values are a little off and that's why you haven't been able to start the truck after loading the tune.
