Default tuned, but low numbers???

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.

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