I need help with my evo its bogging bad when on throttle changed spark plugs took out old fuel have no leaks in the boost I bought it from the auction and i dont know if the previous owner tuned it or not. I can't seem to figure it out I've tried everything now im seeking help from the community. If anyone out there lives in north west houston near 249 and north houston rosyeln I'm seeking help to see if anyone can check it out and help me diagnose it. My contact number is 713-834-5466 (Patel)

 

contact mrd the can help you out

 

Hey I tune, I taught the guy at MDR to tune, I'll diagnose your car for free and if you want it tuned it would be diff. but I don't mind helping you research.

Honestly, I have had both these guys tune my car and Mike at MDR has done things with my car that I did not know were possible with a stock ECU. It seems like every time when I would get my car tuned by Hellcat he would run into a problem and have to call Mike at MDR. Mike will take his time and all day if necessary to work on my car plus he has a shop as well. PM me if you have any questions.

 

Bro go to JTran studio on 11715 Veterans Memorial Dr 281-893-5858 they r close to u and they know evo's promise you they can fix ur problem.

 

doesnt sound like a spark problem to me, i think ur in the right direction w tune

 

it wasn't the tune. i took the car to the dealer to diagnose it and they told me the turbo outlet fitting was bent. so they are going to repair it. I didn't know that could make the car bog that bad when on throttle I hope thats the problem.

 

Call mdr performance.

 

Turbo outlet fitting?

Uh, the J-pipe I guess? I see a hefty bill coming...

 

if the j-pipe is bent... perhaps there is a nasty boost leak. The escaping metered air would cause a rich condition and explain the stumbling and bogging on throttle.

The dealer is going to rape you on this though...

 

2nd, precisely what I was thinking

 

they charged me 200 bucks for the service and 50 dollars for the part. The bogging is gone. It was really bad before.

 

Yep, boost leak. $50 for the part? I would think the elbow would be more than that. Wonder if the just replaced the coupler.

 

I was calling mike because you bought those injectors from him and were wrong about what size they were. i have to know to tune them
