As the title says, i replaced my mrev2 and took of the 5/16th with my stock lower plenum (for borla testing) and after it feels more powerful and that it has more torque. My first and second gear RPM's seem to rise faster as well.

I dont think it is in my head or psychological at all.

Does any one have any thought for the reason for this?

thanks

 

try dynoing it first...it might have been the car just readjusting to the difference

 

Placebo effect.

Could have been better weather conditions, could be an error in the butt dyno.

 

Alright, definatly. see if I can find a place around me.

woke up and drove it this morning... still feels better.

 

I doubt that...

 

I think I probably had an air leak before.

one of the two studs that bolt the lower plenum down were busted off.

 

Maybe you had less gas, than the first time. I have yet to see a dyno where one MD's product lost power.

Recalibrate your butt dyno, that should work.
