I have yet to buy an 05 Mustang GT, but probably will wait until after Christmas or the New Year. So I was wondering what chips are out? Are there any that are legal? And how much HP is each chip adding?

Thanks in advance.

 

get a dyno tune...much better results as they tune the new schip to ur car specificly

 

see personally i like cooler ranch or limon chips, but nacho cheesier is also a very good selection.

I was thinking either Ponch or John?
