Tonight i went to the track to run my car. my first run i was running on low boost but didnt have a chance to use the two-step, on my 2nd run, i was using high boost and used the two step. when i launched it, it felt like it bogged out but it didnt. to make a long story short, blk smoke is coming out and my car is running lil rough, but it will drive but only under 3k rpms. one of my friends told me that maybe one of ic pipes came out or a vacum line came out. Someone said that i might have spring a rod or something dealing with the valve or something. Any opinions would be helpful. thank you

 

Tune ? was it fine before?

 

you cant boost with an intercooler pipe off.
black smoke is fuel. you probly have a ****ty tune, who tuned it
does your engine make any out of the ordinary noises? my guess is you fouled a plug. bring it to a good tuner.

 

yes it was tuned and it was running rich before tuning it.

if the ic pipe came off would car the feels like it's going to kill or something b/c when i start my car, as long as i give it lil gas it stays on but as soon as i take my foot of the gas then it will. Corr Performances did the tuning for me. with the engine, when i rev it up slowly, it rumbles and smoke comes out of the tail pipe. I had fouled a plug, a spark plug?

 

see how they look post some pics when you pull them out. Make sure you go through the car make sure everything is where it needs to be you know vac lines, ICP, normal stuff.

 

shark white smoke is headgasket right?

 

ok. i found the problem, the problem was that on the lower bov part, the hose came off the pipe, maybe due to the hose wasnt on there good enough or the clamp was tighten good enough as well. everything is running better now.

 

too much fuel you need a tune

 

Sounds like it is running rich, like mentioned previously. The leak that you described would cause it to run excessively rich at WOT as the metered air is exiting the system before entering the cylinder, but the ECU doesn't know this so injects fuel based on what was measured at the MAS. Therefore, much more fuel than is required for the amount of air entering the cylinder: black smoke, bogs, running like ****, etc.

 

sounds to be rich maybe
