i was expecting a good 160+ WHP w/o WMI and with it 170+ whp. im sure its the tuner to be honest...

Yup - me too. I'm usually a pretty realistic guy when it comes to stuff like this, and I was seriously disappointed.

Having said that ... I did what Steve suggested all last night and fiddled with the fuel, timing and water-meth ... and the car is making waaaay more power now.

The wideband made it possible ... and the sensor is in a good location sampling the exhaust from all four cylinders so I have a high degree of confidence in its accuracy.

And so with quite a bit less fuel, quite a bit more water meth and more timing - the WOT A/F is still at 11:0 to 1 (which is where Pat said he wanted it to be) and the car is much, much stronger.

Having said that ... I only had +4 degrees of timing and -6% fuel to work with and the water meth (smallest injector) is wide open - so I'm basically done with the parameters I have control over.

Having said that - the car feels like it has a lot more to give ... it is very quiet, runs very smooth and feels very unstressed ... so with more water meth, a bit less fuel and more timing, I'll bet it could be even stronger. It still has bags of torque right off idle and to Pat's credit the power curve is absolutely straight right up to the red line ... so the feeling is that it continues to pull hard all the way.

Thanks for the suggestions everyone ... I still think I have more work to do ... not sure paying a tuner and basically being at their mercy is in my future however ... I think it more likely I will buy the appropriate software and learn how to tune the fofo myself.
