Hey Shiv, my buddy and I (he has an IX with MBC and Jegs Cutout, No Flash!!) were "accelerating" on an on ramp from about 40mph up to 80 and I couldn't shake him. He stayed right there with me all three times.

The thing is that he is only runnin 15psi!!!! I have an MR, with the stock gauge saying 1.5 bars of boost. My boost controller confirms that. I have the Cam gear set at 0 and it runs smoothly.

The car pulls hard from 4k-5k, then it flattens out from there till 7800. Is it a problem with the flash? I have a check engine light with a P0300 multiple misfire code, and I'm running straight 93 octane.

Please Help!!!

P.S. we were NOT street racing, merely accelerating to cruising speed for the interstate

U have an intake or is HKS RS a Bov. BTW IXs are beasts.

 

Intake

 

Stock intake with high flowing drop in is preferable and the norm for a Vishnu tuned car. Likely your power issue.

 

sometihng is not right. a bone stock evo 9 will pull away from a car boosting only 15 psi. either he is boosting more or there is something wrong with ur car.

 

you think it would make THAT much difference? he has stock everything exept a cutout and mbc. I have spent over 4k on this motor, and it just sucks!

 

I also got waxed bigtime by a Mustang Cobra 05 yesterday.....he pulled on me at a 10mph roll like I was stopped.

 

there is no 05 cobra.

 

04.....my bad....anyway it was supercharged and it destroyed me.....through 3rd gear, and I shifted pretty quick, and he even bounced the limiter in first!

 

Those cobras are no joke... so r you only running 15psi or is the 9 why would he get a mbc and turn down the boost?

 

No. My buddy is running 15 psi because he turned down his MBC (dunno why) Im running 23psi dropping to 21.......

 

Maybe he's lying to you about turning down the boost?

 

nope....i had driven his car just before, and you have to pop the hood to adjust it. Even then, with my mods, I should have pulled on him without even trying! He doesnt even have a flash!

 

You should get your car straight before running it hard with those mods or your next thread will be "I just spent $4k on this motor and all I got was this lousy broken piston". It sounds like you may be running lean or knocking after 5k and your ecu is saving you from destruction. Throw your stock intake back on and see how she runs...

 

so you think its just the MAF and I need to swap intakes......that would suprise me, but any information helps!
