it may be a bit hard to explain what I am actually dealing with most of the time I have to be on the maintenance throttle very quickly and there is a slim line between keeping the car steady or causing a lift off oversteer at those speeds ..

Like you mentioned those transitions may be somewhat easier with sportbikes, I used to own two of them (Gixxer 600 and Ninja 1000, and totaled both of them within 8 months, long story lol) and slipper clutches were great help ..but as you can imagine fast in - fast out requires some serious "man berries" on motorcycle and maybe some serious experience with trail braking technique which I never experienced on a motorcycle

I will try getting a lighter flywheel as you suggested and am hoping that it will help me at track days..

I just wanted to say, if you haven't clamped your evap hoses do it now. I just did on my car and now my AFR's are where they need to be. They were running way lean and now so much better. The evap hoses slipped off with a pinky finger. I don't know how they correlate to my tune but now I'm running exactly where I should be when open and closed loop. No more air blowing sound when under boost too.

This should be step one before the SC goes on because it's a pain to do after the fact.

So, after a failed hour of searches, I ask you guys this: where is a good place to tap in a boost gauge? I'm using Torque App right now and it kind of sucks because i get vacuum until like 5000rpm on WOT. I bought a cheap gauge (don't care too much about accuracy, more so just the presence of boost near correct levels) but i don't know where to run the tube to. any suggestions?

I teed off the brake booster.

I'm getting a code p0507 idle air control system rpm higher than expected, my rpms at idle are 1300-1000 sometimes higher, I clamp.the 3 hoses under the intake manifold any a idea what else could be? Maybe I missed a hose? Or maybe is something else?

yup, usually caused by a vacuum leak. gotta find it. thats the same code i got when i blew off my EVAP hose

what kind of readings are you getting?

Around 10 psi I think. I don't really watch it much. More interested in AFR.

what about vacuum?

That's like negative 10-15.

at what RPM do you start seeing 0 and boost?

[captain_jack]

When mine was installed i was seeing boost at 2k, well according to @nelsmar when we were on the dyno.

Between 2K & 2.5k, but it really depends on how you drive I think. Like on 6th gear until you floor it and let reach boost. But oh boy it's so easy to reach over 100 mph... I need better tires.
