Hmm... ...
I was only hitting 1400 pre turbo @ WOT.
When I had 100hp injectors (ats 20's), Drag Comp, PDR40, Afe cannon and thats on 5x5.
Sounds like your running a little hot.
Just my opinion though.
W/ 125hp injectors I am now hitting 1600 and this is with an autometer gauge.
Back when I had a stock turbo, I could hit the 6 O clock position with the autometer w/drag comp and 100hp injectors.
