Lots of boost and getting nervous

I just installed a new TiAL 38mm waste gate the other weekend and the NoVA rain finally let up to let me take it for a spin. I can say with certainty that my boost is more consistant than it has ever been.
My concern is that I am consistantly running 20.5 lbs of boost. I am currently running a o-ringed cylinder head with a WFHG (but probably pushing that thresholds limit). My A/F gauge is on the fritz so I am looking into that over the weekend to see it I am running too lean.
Any thoughts on if this is normal and what I should be watching out for?

I am running Weltmeister chips and no fuel controller as of yet.

TURN DOWN THE BOOST AND STEP AWAY FROM THE LBE ![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)
Dial back the boost to whatever level you were running before the Tial instal.

Steve, are you using the LBE in single port or dual port?
Here's a good thread: Dual Port WG MBC setup

I am sure those chips are only mapped for NO MORE THAN 15PSI! If you are running more than this you are probably running very lean! I would not run like this until you have some A/F control

I will address my A/F gauge this weekend and see what that is telling me (for the record is a narrow band gauge..I know, shame on me). Secondly, what are my options with addressing the likely hood of not enougth fuel? Would a 3.0 bar FPR add any benefit at this point? Lastly, should I consider new chips or, ideally, the piggy back system from Vitesse?
Unfortunately, my pockets only go so deep and I have to take baby steps for my "project car"
Regarding the LBE, that is coming out. The only reason I had it was due to the fact that at the time I did not have budget to get a new waste gate and I used it as a stop gap on the OEM waste gate.
Thank you for the answers and assistance thus far.

Just turn the LBE down until you get an a/f reading.

Me too, the Lindsey website says that it is pre-set at 10psi.
I also have the Welt chips in my car and from what everyone has told me, they are designed to be used with the 3 bar FPR, and wastegate shims or upgraded WG.
Also, the Welt chips are mapped to 15psi.
Be careful.... 20psi, lean A/F ratio, and improper chips= disaster

Is the Tial installed correctly? if the tial is installed backwards, it will run high boost no matter what the boost controller setting is.
