I had my Z tuned last year on AAMs dyno Mike tuned it perfectly. My air fuel ratio goes from 13.5 through 13.1 across the board. My max power is 270 and 235 torque uncorrected in my auto. I was wondering if i got a utec or eu if i could make more power? Please give me some feed back everyone.


Thanks Glen

 

IMO it's most likely not worth it to spend the money on a UTEC for N/A, but that's just me. ESPECIALLY when you've tuned it once already.

Would you really want to drop $1k + tuning then find out you only made 5-10 whp?

 

Its not worth it especially after u got the AAM tune. U wont see much in the peak, but maybe some more thru the midrange. UTEC is really for the fine tuninng and getting it smooth

 

If you plan to add mods to your car, especially TT, ST, or SC it is definitely a worthwhile investment, because there exists no better engine control device on the market IMO.

But if your plans are to stay stock, then I would agree, you probably won't get much out of it.

My problem is I rushed into FI only to later find out how out of control my engine management was. The BullS*** EMFU(brain) sold with the ATI kit does little to actually control the engine. I wish I had a UTEC..NOW!!! Hopefully once I get that, some bigger injectors, fuel pump and return fuel lines I can blow the hell out of my car and get to the 400hp goal.
