Two weekends ago was my first track event since installing my Defi boost gauge, and it recorded spikes on downshifts fairly regularly reacing 17-19psi and a maximum spike up to 24psi. To be clear i'm not talking about blips up to a peak with the throttle body closed and a near instant drop to normal levels after acceleration resumes, I'm talking about a moderate fast build and it holding for a second or so then falling off.
Got fed up with the problems and figured I'd rather have 70 less HP and be on the track than be sitting in the paddock, so I took it out and continued to record with my boost gauge. I saw throttlebody-close-style blips up to 11psi with the procede removed and on boost runs peaking at 8-9psi, i.e. what you'd expect.
I'm going to stay stock for a while and work on driving, but I was wondering if anyone else was having a positive track day experience with any of the available tunes. I'm going to want to add one back when I get my driving skills where I want them.
