ok you got a point lol i ran bone stock a 13.9 at 101.69 but like i feel the difference of when the car wants to move and doesnt. also i forgot to mention that ma turbo is making a different sound when it spools up liek a louder screamin sound that it never did before

 

when was the last time you changed your plugs and wires? you also should retune your wga/mbc to a 18 spike holding 15 or so.

 

i cahnged mine not to long ago. because i had a misfire. so i changed the plugs wires and coilpack. i took my manuel boost controller out and it seems to b alot faster. maybe that was the problem since i was boostin so high then held at low boost

 

When my turbo makes a louder "scream" than usual it is because it blew out the airflow sensor in the intake tube right before the throtle body. I eventually had to use a long wire tie to wrap around the tube , between the two little wires and over the top of the sensor to keep it from blowing out about once a week.

 

my codes are P2074-MANIFOLD PRESSURE/THROTTLE POSITION CORRELATION
- HIGH FLOW/VACUUM LEAK for me to fix that wat should i check

 

your car only "feels" faster with no mbc, it's actually not. you probably had it tuned wrong. set the wga to 12psi and the mbc to 15 or so.

 

It may be faster if it's not spiking to 20 and hitting fuel cut .... but ifyou setit upcorrectly likePSI just told you it will be better.

 

i took ma boost controller and it feels alot fater it goes to like 16 or 17 psi holding no mroe fuel cutout. but it sais p2074 vacumm leak maybe that could be the problem or why is that on.. wat effect does it do to the car and how would i fix that. for me to turn it to 12 on the wga how would i do that clockwise or counter clockwise

 

if you make the wastegate arm longer is less boost...the shorter the more boost...
