Well, my car seems to have its fair share of issues, this one is very VERY interesting though. Upon a cold start (after the engine has warmed up mind you, I'm not beating on it while it's still cold) it seems as though my computer forgets everything it has ever learned.

Let me elaborate, as you can see from the title, I managed to look over and see around 20+psi today... yes, 20psi... This is a STOCK SS/TC with ambient temp at around 36F. Normally I see roughly 12psi on any given day. I had experienced this previously, but not with the results I had today. Normally upon a cold start situation, first hard acceleration would... shudder a bit.... This time it just PULLED far FAR harder than I've seen thus far. As I had experienced this previously, I decided to fire up HPTuners before I went out and do a little logging so I could get a bit more info as to the cause and the problem.

Let me just say this, looking at the log now here's some fun little numbers, pegged the MAP sensor, 29.91lb/min MAF, 296% absolute load (SAE), 1.75g/cyl Calc'd Cylinder Air, 187% Air Load at one point when I let off, and it was still pulling strong (and gaining).

Now the question of the day, what the hell is (wrong?) with my car and how long do I have to wait for the stage 1 kit to get this 24/7?

 

here we go again...

 

Did I miss a thread on this somewhere? Or did you misread and think I'm talking about lost pressure?

 

ha kinda both....it comes up in tons of threads (why they are boosting different all the time)-LNF design. Also that yours seems a bit original and we now how to figure that out. One thing changes and the LNF altars things to compensate and the big one is boost.....but being so cold you should be less. Might be losing some pressure who knows. There is a thread with a link for an upgraded BOV spring. ??? I'm not clear if this is aso for the TC as I've not looked into it too much.
