to the oc , it doesnt matter what power numbers u have , jus as long as it gets to the ground, i dont care anymore about what my hp numbers are, i simply hit the gas and let the losers try to guess!! maybe my car was a freak motor, but either way go and get it tuned for the most power safely

Thanks! It was TOO much power for daily driving if you ask me, especially since the turbo had plenty more left in it (20G I think it starts operating at its best around 22-23 psi??).
At the time it was my my only ride, so it did double duty as my DD and fun car. Even with the 3-port (never got around to getting MBC) it was crazy responsive and smooth. I did have it re-tuned twice to get it how I like it, power delivery vs top end tower. I think I was in boost and had pretty much full torque around 3,200 RPM? I usually chose to use 2nd gear from dead stop when just cruising around town I am trying to look for my dyno sheet right now.
But as always, it comes down to working with the tuner to figure out what you need, how you like your car to get tuned and make the best out of the mods.

I am a fan of the 20g as well particularly for the power lvls you are looking for. I believe those power numbers can be done with a smaller turbo but why? You may need injectors and a fuel pump too.
I think a td05/20g probably 7 cm as it will give you more power and grunt down low where as the 8cm will give you a higher yeald in numbers but at the sacrifice of putting it higher in the rpm band.
Good lucka nd happy motoring.

ok there must be a misunderstanding here, ed's laptop does read low, so u have to had 20% or so to match up with high reading dynos, i merely stated the high reading dyno numbers. btw yes its aggressive but at the same time very safe, he put me at 19.5 psi, but for what i have or lack there of, my car puts down more power than some subies with way more parts applied, i guess its good for me. we shouldnt be chasing numbers anyway, jus chasing pure performance!!!
