Hello I have a problem with my setup...

here is the setup:

GTRS
Unitronics
Greedspeed FMIC
neuspeed TIP
bosch Green Giant 440cc injectors.
VR6 MAF housing with stock MAF sensor
APR 2.5" exhaust
testpipe
ATP Manifold.
Evo MS DV
custom intake.

the problem:

1)I am pulling about 8 degree's of timing in the upper rpm range.
2)The turbo lags a lot (hit 20PSI by 4400 RPM's). 3)My MAF sensor only reads 200g/s when it should be around 300g/s (specified by unitronic)
4) my long term fuel trims are at Idle -4.5%, part load +17.5%.
5) the car does not start right away on cold starts it takes about 5-8 seconds of cranking over to start
some things you should know...
1)I have a Brand new MAF Sensor
2)I just changed the spark plugs
3)The A/F ratio is spot on... requested vs. actual are right on with each other.


Please Help me
thanks

 

it is very similar what I have. I also have fpr which runs at 44.1 psi.
You can buy and put a fuel gauge which is like $10 a local place.

How about your plugs ?

 

I am running NGK BKR7E gapped at .028", I think ia m going to go down to the local auto store to pick one up....

 

it's a cheap and worthy mod specially a car like yours.
