For those of you that religiously change your synthetic oil at 3,000 miles because you are worried, send a sample to BlackStone-Labs next time you remove the oil. You will see the viscosity still around 97-99%, which means you are removing good oil. They rate synthetics at higher milage for a reason

 

Even the manual says to change your oil over 3000. I just bring it back in when my dealer tells me to; i'm done fighting the "best time to change oil" battle.

I just got a EcuTek flash on my stock Evo, it seems louder, and the overall feel of the car has changed dramaticaly.

Check this thread out for your 300 whp goal, https://www.evolutionm.net/forums/sh...ghlight=ecutek with a MBC and racegas you can exceed your expectations.

 

Do you notice it most at WOT?

 

The noise, no, most at idle. The power delivery, yes WOT.

 

Thanks.

 

Yet the flash changes nothing in closed loop - it can't change the sound unless at WOT (open loop).

 

Yeah, i also thought it was weird my because my exhaust gets little puddles under it and lots more visual exhaust when warming up at idle.
