b16 stock
t3/t04 garrett 50 trim. a/r .42/.50
38mm wastegate
meutek manifold
2.5" to 3" dp w/ 3" exhaust - hi flow cat(magna flow)
tune at 10 psi
no dumptube
450cc dsm w/ resistor box

look at the graph link--- http://viewmorepics.myspace.com/inde...ageID=12175133

the numbers are low for b16.
what can be wrong? any body?

the tuner say its too much backpressure.... which is the cat that cause it.
also i don't have the dumptube running down the engine bay.

 

wtf?


boost psi?

you dont have the dumptube running where?

those a/rs are small for a revving engine like a b16 in my opinion.

there are alot of different things that could cause that.

i dont know what the ---- they are, but i do know that it would be easier for people to answer if you had a more detailed description of what you are running.

 

my bad, some updated infor

 

stock exhaust on it, right?

 

no, i have a custom 3" exhaust on it
with high flow magna flow cat.

 

i found your problem

 

Create a dump tube and find a better tuner.
Make sure that the valves and the timing is adjusted properly too.

 

retune

 

all of the above and that turbo makes more heat on my ls

 

so you ran this turbo before?
what kind of numbers did you make?

so i need to re route the dumptube
change cat into test pipe
the timing is change by the tuner
