how many of you are actually hitting target boost and tappering off to 18 psi +/- 1.5 at redline? im curious as my boost peaks out at 25 and drops to around 12 by redline. my mods consist of intake and TBE if that has any relevance to this.

On my logs they peak at around 25 and tapers down to 15 boost pill is still in though.

iv removed mine in accordance with cobbs instructions, but still what your saying is that your boost is falling off 3 pounds lower than what the map claims. i wonder if you remove your pill if this would only get worse or better...

Are you running a HFC or a test pipe?

i think im going to try first running the wastegate arm to the "18 psi" position and see what it will hold to redline, since according to cobb im tuned for 18 psi to redline.

ok so i cranked up the wastegate arm to the "18psi" position and here are the results before-blue line after-red line. according to my logs im holding only about 1 psi more across the entire rev range. my next step is to tune using the GS 3 port i just got and see how well that holds boost over the stock solenoids. i know this turbo hits a wall at upper rpms but theres gotta be a way to flow closer to 18 psi to redline with it. looks like a fp green, dom 2.0 or bbx lite may be in my future...

before i started tuning my car on the ots map with just the aem intake and hi flow, and catback i usually hit 25.9 psi tapering down to 17.4 at 7k. now im hitting 23.9 psi but taper to 20 psi at 7k, mods in my signature. 12 is beyond low even on a ots map
