Default 05 cobb ap question

I just installed my AP S1 on Friday and I was really impressed with it, great gains and response. Being the tweak that I am I loaded the valet map just to see what it would do.......5 minutes later I loaded the 93 octane s1 map back on there and went for a drive and my boost was only hitting about 14 (live boost on the AP) instead of 16.5ish which is what it was hitting before.

Is there a learning curve?? Any ideas on why I'm hitting about 2 pounds low now as opposed to before?

TIA

I believe there is a learning curve. Drive for a day or two then see if you are still not hitting target boost.

Also, am I supposed to make more boost in 3rd than I am in second and first? I just realized that in 3rd+ gears I make 3PSI more than in the first two gears....

Yeah, coz in 1st & 2nd gears, there is less *load* so boost is lower. Load can be determined from throttle position sensor or more, and the acceleration of your car. That's why when you going up hill or pull a trailer, the boost will go up.

More boost in 3rd is normal and yes there is a learning curve.

hopefully it will be "learned" by friday...
Also, with the AP is it necessary to do the timing multiplier trick that vishnu posted??
