I bought my Evo back in December of last year...so I've only had it for just under 2 months. The car when I first got it felt great, everytime I hit the gas pedal I felt a surge of power. I got an AMS baseflash...and then that surge was gone. Thinking maybe it was just me, I've been daily driving it waiting for my stage 1 stuff to come in.

I punched it on the highway tonight coming home from work...and the car just didn't seem like it was fast anymore--it didn't have the surge from before nor did it seem to accelerate like I remember it when I first got it.

Is it possible that a brand new car could have a boost leak? Or am I just simply getting used to the car?

 

yes a brand new car could possible boost leaks ! ..

and mostly,it doesn't get slow, you got used to the power too quick ! ..

 

You probably just got use to the power. You may also try cleaning or replacing your stock air filter. It seems after about 5k it doesn't work as well. Replacing/Cleaning it may revive some performance.

You could also try reseting your ecu by disconnecting your battery cable for a few minutes.

 

I have the same feeling after daily driving my car. I usually drive my wifes car for a day or two to make my car feel quick again

 

u are prob getting used to it. time for mods!

 

umm... ur just getting used to the power... i've had mine... and one i got used to it stock i started modding... and it's starting to feel slow again... so here we go again with the mod's

 

yea i aguree, u probably got used to the power and that made u think its slow. put it on dyno, only way to tell

 

I agree. Take out another car for a couple days and then go back to the evo and see how it is.

 

not to hijack but whats normal vacuum levels for a stock IX?

 

I think you would get used to the power no matter hosepower you have, that is until you get to 600whp?

 

Dont worry its not getting slower your just gettin used to it
Mod up though!

 

I hate that feeling of "getting used of the power."

 

Hahaha. I feel the same way. I got used to the power.

 

do you have a boost guage? If not get one with ur tax return.

 

yes you probably got use to the power
i never always thought stock evos were very slow though
