That is pretty good for a TD04.

i would like to see the dyno graph with afr readings. 11.1 is a good a/f but 22psi is a lot of hot air coming out of that little turbo. i would be afraid of detonation. do you have a scan gauge that measures knock?

either way it's a good time.

I have no dynographs because it was a road tune.

He data logged it for about 2 hrs with tons of wot pulls and never got any knock

i was always told to shift right around 5.8k to 6.2k and 22psi out of a tdo4 wow i only ran 16psi. your injecters stock? other then that good time. i wonder what mine will run at sea level after all my mods

[epicroot]

22 psi is very high on 93

My tuner told me that my car just kept taking increased timing and that 22 psi isn't hurting anything. No knock no detonation

I always get weary of those who just add timing to quell knock... :-/

Idk much about tuning.. he's a reputable shop so I hope he knows way he's doing..

ok so im like really lost after you go past 19 or 20 psi dont they stock TD04 become inefficent and all it does is blow hot air?

[epicroot]

Yes im sure its out of its efficiency range.. on e85 maybe not but on 93 def...

I recently had aconvo on nastyoc about this..

They came to the conclusion that id run the same time maybe even better setting my peak psi at 18

I don't know anything about tuning so I really have no clue...

If 22psi isn't efficient why would the tuner run it up so high

Because he doesnt know what hes doing maybe???? my car has been tuned by 4 different people(moved around a lot) and each of them on my stock turbo never went past 17 psi. I think you might want to discuss this with your tuner and see

[epicroot]

His shop specialises in subarus.. its really about all they work on.

It depends on your atmospheric pressure and inlet temperatures (and intercooling efficiencies).

This is some good info:
EngineLogics. - How to read a Compressor Maps

On the stock intercooler, stock turbo, at sea level and standard temperature... most tuners seem to suggest 20 PSI is the maximum efficiency... I can crunch the numbers later.
