I was wondering what boost level people are targeting when they are using their 2 step on regular street tires?

i recently got my 2 step working & would like to hear what works best for other people / recomendations / experience.

i am also on the oem clutch, but i dont know for how much longer!

i have a fp-grn....you may want to note what turbo set-up your using too.

TIA

I can get between 8 lbs with an OEM timing map and up to 16 lbs lowering the timing at the 2-step load cells....but I keep it at 8 lbs so that the wheel spin isn't crazy!

I did 2 launches today on 1 setting...holy $hit!! the car just put me into the seat....

i was @ 22 & 20 psi for both launches...... i can reduce the boost by tweaking the settings...

i launched @ 5500 revs......i was ~0.5/0.6 secs quicker accelreating to 60mph as well.

I plan on reducing my gap between fuel cut & retard rev to reduce the lauching rev boost level......that is why i made this post.....

i would think something in the region ~12/14 psi???? pulling htis number deep from my ass...teroid

Right now, my 2step is set at 6k. I get around 8-10lbs of boost off the line. I have a BLOX boost gauge but its possibly off my 1-2psi give or take.

I have hit like 1.78 or 1.79 60 foot with 8 psi on the stock turbo and a stock clutch. RPM on the stock ECU was set at 5700.
