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.

I’m going to go with not possible. That would be a 50% power increase. Not a believer in these quick chips. If the engine had that much more to give, I’m sure smart would have upped the HP from the get-go.

Performance improvements are sssooo much easier with the 453's... UP DA BOOST!

If you had one of those, tuning gains are relatively easy. Sorry I wasn't much help, I personally wouldn't try too hard to make a 451 faster.

But a 453...
