Are there any affordable performance chips for a stock 2011 Smart Passion? I see one on Amazon for about $70 that says it gives you 35 more Hp and 5 more mpg. I think the name is something like Innovation. Is this really possible?....or is it really a computer "work around" that the cars computer will eventually figure out? I've always figured that if something sounds too good to be true... :shrug: But I have no idea so thought I'd ask. Thanks for any input folks.
