And the end result is that it feels like I've LOST 10-15hp ?????????????? (instead of having gained 10hp which is what I was expecting)


I was expecting to awaken a monster
I was expecting more noise
I was expecting some added power in the top end



Instead …………..

It feels like I'm driving around with AirConditioning on (I don't even have AC) with 3 passengers in the car (when in fact I've actually taken a bunch of weight OUT of the car)

I'm at a total loss.



If this is the way its gonna drive, I'll switch it all back to stock.

I would ditch that thermostat, that is way to cold, no reason at all for that on a street car - much less in the great white north. The ECU is probably dumping fuel in there in an effort to get the temp to what it thinks is normal, rich does not make power.

- Its never driven in the Winter

- Its only driven in summer (when our average temps are probably as high or higher (with humidex) than Sunny (dry) California and southern States.

- I've been keeping tabs on Intake Air Temp / Water Temp / Air-Fuel (among other things) and none of them have seemed wonky, but I'll go back and pay attention to the AF ratio while doing "pulls"
