More boost with HPTuners?
 

Have a buddy with hptuners and I was wondering what all my options are to get more than 21 PSI out of this thing. Got a 12.3 afr across the board and put down 287 hp and 310 tq with it being 88 degrees out and 35% humidity. I'm disappointed with the numbers and want about 23 PSI out of her. My friend is experienced with tuning gm motors (mostly gto's and vettes) and I'm the first turbo ss he's done. He has experience with boosted cars as well.

Any help is much obliged.

I know you want to stick with HPtuners because of your connection... but if you decide to go another way, look me or Mkulrey up!

maybe see fred at SMG, i know hes got them to make more power than what youre putting down

if you want more power get a trifecta tune with hp tuned on top of that
trifecta can do more things then hp tuners can

The SS/TC LNF is a totally different beast to tune than a gto or vette. It uses a torque based controller and has to be tuned totally different. My advice, get a tune from someone familiar with tuning LNF motors or you will have problems.

ur afr is a little low for the lnf... I suggest finding someone that tunes DI engines or specifically the LNF.
