Ok my car is really acting wierd for the past few weeks.... its spitting out black smoke at partial or full throttle... its getting 10mpg on good driving
Also the car doesn't hit full boost till 4k

it breaks up and jerks driving at a light throttle...

i really dont know what it is...

also it runs really slow... like a stock srt beat me... and i usually just pull and pull

Mods are:

Utec
Pruven IC
XS IC pipes
Megan Header and turboback
EVC5
Megan BOV


so my BOV broke so we replaced it last week... but i think its way too tight becasue it doesn't blow off until 1.0 bar or above... which wasn't how my old setup was but i dont think that has anyting to do w/ hte car as it is now...
I also dont think its the turbo because im pretty sure its fuel being dumped out


I thought the car is misfiring because its plugs are bad (were ngkbpr8es) changed to ngkbpr7es this time... car ran a little better but the problems are still there

Im currently at a half tank with 57 miles!!!!!!

Im hoping someone on here can help me

 

You are running too rich. Get your tune checked.

Any codes ?

you're running way too rich, it's going to foul your plugs again in short order. Why would you think it's not the BOV? That's what you worked on, and that's when the problem appears to have started. It sounds like you are leaking out a ton of air that the MAS sensor as already registered. Maybe the connections at the BOV aren't tight? Look for any leak source on the intake tract.

 

i would check for any boost leaks. make sure all your hose clamps are tight and see if it makes a difference. a pressure test is also a good thing to do if you haven't already. good luck and let us know what you find.

 

im going to try those... but i dont think i have a leak... i did notice my boost gauges were rewired, the defi is run off the fuel pressure off the intake manifold... in the beginning i did that once and it caused the car to run funny and lose power... but this problem is progressive... ill try that also and see what happens
