I have a 04 gt with Full exhaust, edelbrock victor jr intake manifold, mmr sheet metal upper, 42lb injectors, edlelbrock rails, 255 pump, KB BAB, Vortech V1 S-Trim w/ 3.33 pulley, 3 core front mount Intercooler. Ive had this thing dynoed and it only produced 350rwhp at "10 lbs" i was looking around to see if I can find leaks and I found that the BOV at idle is pissing a **** load of air and the vaccum line for boost gauge is ran off of the BOV is well so Im wondering if it is making 10 lbs at the BOV and not at the motoe because of a possible Boost Leak.This is my setup.
This is the cheap BOV.

 

my BOV was ****ty as well leaking at ideal real bad. I wasnt able to build any boost like i should of cuz of quit a bit of leaks. Bov, intake manifold, iac vent, coupler and a few other spots. I replaced mine with a procharger bov.

 

where you have yur oil breather is one of the spots that leaked for me.

 

Did you use the red race blow off valve?

 

Damn man that sucks.I bought the Tial Bov, you guys heard about any issues on those?

 

Jeesh man...thats a tad low.

Good luck w/ finding the issue..that thing should be 410 easy.

 

was the car tuned or just dynoed? if it was tuned i would find a different tuner who knows what they are doing

 

I have my oild breather caps on the valve covers and I noticed that the one is turning black on the driver side head and they are red new and the other still looks perfect.

 

It was tuned and everything, we started at like 730 am and worked on it until about 3 looking for reasons why this thing isnt performing like it should. Hes a good tuner and he has a 1000rwhp turbo notch. He didnt even charge me for tuning it because he cant find out what the hell is going on with this thing.

 

Thats the one I believe thats on mine. Cheap ebay garbage.
