With a tune they usually move the rev limiter up but you shouldn't have hit 7400. If there's no parts on the ground you should be ok.

 

Phewwww these posts make me feel better, it was running good today so im not too worried anymore about it. I'll check the rev limiter it seems to shift around 5800 - 6000 with the tune at WOT, I think the rev limiter must have cut the gas when I hit 7K and up I just probably didn't know. It didn't bounce but no parts on the ground lol! So Pheeww!

 

Don't feel bad those of us with 2005 and up Mustangs have to make sure the traction control switch is off before we manually shift gears in an automatic.

 

The stock valve springs may not like that kind of reving. Especially if you're going to put that big cam in futur mods.
