Default For 2-bar SD turbo users...do you "feel" your car making boost?

May sound stupid, but when I was tuning in 1-bar SD I could always feel the "sucked through the seat" sensation when I went into the boosted zone. With the 2-bar, I never feel it. No sucked into the seat....no holy $hit, nothing. Don't get me wrong, the car hauls a$$ (obliterated a bolt-on 2005+ Mustang GT yesterday) and the car put down 453/432 SAE at Va Speed's dyno 3 weeks ago. But, it just feels like powerful N/A nowadays and not FI. On the dyno there are no sudden spikes of power or torque. Just a smooth creep to 453. Torque hits 400+ by 2800RPM and sits there till 6000RPM. Thinking this is the reason for the "lack of sensation"?

Am I just used to the boost (5PSI BTW) + the 2-bar tuning? Do you other 2-bar SD users ever notice the same? I know my HP/torque curves are pretty smooth, but I always think something isn't working right w/ my car because of this

Again, may sound stupid, but it does bug me. $0.02 appreciated

probably the smooth delivery. First time i drove my T/A i thought that it would only run 14s but the clocks kept giving me 13sec slips because the torque curve was so broad and smoot

When I get the "my car feels slow" sensation, I just turn it up. That usually takes care of it for a few weeks.

Thanks. I am hoping a few suspension tweaks and some new slicks (these ones are couple years old) we will see a 9.xx on 13 pounds and 91 octane. Sorry for the

Thanks. I was thinking of getting greedy and installing my boost controller (I made a concious decision when I put the turbo in NOT to install it ) Thinking w/ low comp heads and FMIC I could probably get away w/ 8PSI now

Mate crank it up, I run a low setting of 8 psi and high setting of 12 psi on my Greddy with stock bottom end.
8 feels slow but 12 is a little more fun

I just got mine set up to run 8 psi, 2 bar SD, and I still get that holy crap feeling in my car. Bu that could be the size of the turbo too....what size are you running?

It also could be that I'm running low compression, and the difference between 0 psi and 8 psi is ridiculous, so I notice it more??
