OK so yesterday i took one of my good Buddy's for a ride in the Evo, i went to launch(got the 2 step) the car and when i slipped off the clutch the car puttered like 3 times and i heard a back fire.

every since this the car is acting real weird, when im in 2nd-3-4 and i get on it, the rpms will jump up a 1000 then fall like 500 then take off, i am making full boost while all this is going on.

i went on the highway and did a 5th gear pull while at 60mph(2000rpm) the car slowly started going to 2700-2750 then it went to 3k stayed for a split sec then started to take off, rpms never fell.

I also got the dynoflash(base) sometimes when i do the 2step the boost will be at 1.0bar instead of half. never took off while at 1.0.

i dont know if its my clutch going or something to do with the boost. i hope some of this makes sense....

My mods are Dynoflash,drop in k&n and an magnaflow axleback muffler.

 

Check your intercooler piping, you sound as if you could have a leak somewhere. Sounds like a coupler could be "spreading" under boost messing up your fuel map.

My 2c.

 

I did check all the clamps on the intercooler and the ic pipes and all are intact.

God i hopeing its not my clutch btw i only have 26k and i have no SES lights on.

 

sounds like your clutch is slipping.

 

Yea sounds like typical symptoms

 

Yes, that's just your clutch slipping. The stocker can't handle 6k 2-step launches - it gets overpowered easily. TIme to replace it.

 

Then mine CAN'T BE stock. Since the flash I have done at least 15-20 2 step launches. *crosses fingers*

 

that jsut started to happen to me yesterday after i launched the car and now my clutch feels wierd and i try to step on the gass in first gear it jsut goes to 3 then jumps really quick to 6-7 happens like this with every gear i think its the clutch i tried puttin my stock BOV back in and it was a little bit better but still the jump from 3000 to 6-7000 rpm dont know whats wrong gonna make an appointment today to get it check

 

Good luck.....You'll need it

Some guy posted this a while ago and it included a video of his RPM "jump" when shifting, it's the clutch slipping, see if yours looks just like that.

 

It also depends on how much you slip the clutch or not. My friend is pretty good at launching his car, he pretty much dumps it and it takes off, and he's done it at least 30 times. His clutch feels fine, the more you slip it, the more the clutch burns up.

 

Clutch.

 

Definitely sounds like the clutch.

 

Yup, been there twice. Ouch. Definitely a clutch.

 

i took my car to the guy down the street he works at the mitsubishi dealer that i got my car from its my friends neighbor and he said that the evo clutch is always slippin and he took a look at my car and said that the clutch is bad so i would need to replace a new clutch which is 112 Dollars and i had a hks BOV and he yelled at me and said that i shouldnt of modded the car and it looks nice and all but he seen many people come into the service center and they get denied warranty so im going to be puttin my stock BOV back in and bringing it in on tuesday and gettin my clutch replaced.
