I have a strange thing happening
When I hit the gas hard the car, what it seems like, is going in 2 stages.
Smooth acceleration till around 5k rpm then it almost feels like a very fast
loose of power then the car pulls again.
I mean its in .5sec but i can feel that double punch.
Anyone knows that that could be?
2012 wrx 1120 miles on it with Perrin intake
take the intake off before you blow the motor, and get a tune ASAP with or without mods.
the OEM tune is junk and knocks like crazy. the pulls you're feeling is a knock event and the motor pulling 2-4* of timing and then giving it back to you. that more then enough to blow a piston ringland.
I took the intake out and OMG, car run soooo much better
much better response and pulls.
Yes, i know ppl are saying don't do it with out the tune
but like most ppl we just do and take it off lol
I guess we hope we wont have to do the tune and get luckey
but not in my case
I did leave the GFB BpV/BoV on
I will call the dealer and see if they would void the warranty
if I tune it and if it will, then I guess I'll wait
3yr or 36k miles
i never understood why people say that. whats it matter if it blows at 3k or 36k? you still have to pay for it if you blew it up. why waste your time for 3 years and 36k to drive a pig around?
and as for saying "i guess we hope we wont have to do the tune and get lucky" is crazy talk! if you arent logging your car you have NO idea if you do or dont need a tune for something. so hoping and praying is only going to damage the motor if you havent done so already.
ive said this a million times so one more shouldnt hurt. the OEM tune is garbage and knocks like crazy. anything over 1.8 load especially in the upper RPMs is death to a motor territory. now im not talking about the motor blowing up and killing you but its enough to crack a piston ringland. once a ringland has cracked you lose all power to that cylinder. sometimes 1 down cylinder cant be felt by your normal everyday Joe. most time the ECU doesnt even know there is a problem. you can crack a ringland for exactly what you have done or you can "micro crack' it. if you pulled the piston and magna fluxed it you'll see the micro crack. however no ones gonna do this. once you start tuning and adding more parts and power the crack will grow and blow the motor. this is why you guys gotta read before you start "hoping" everything will be ok. get off the OEM tune and get a stage 1 tune from someone; sooner the better.
Good question! I have no idea why the hell they would put such a crap tune on a great platform like the wrx. But alas...its there so all we can do is fix it. Good news is I think with a stage 1 tune you will be happier with the overall feel of the car. You will feel a lot smoother acceleration. And a slight bump in power. I vote start at stage one and let the mod bug dig in
Cobb ap stage 2 ots, catless uppipe, catless turboback, Cobb Sf intake.
