Help!!! Can't go over 20 pounds of boost.
Hi
I need your input. Today I went to Akuma Motorsport to get dyno tune. John from Akuma run few runs on the dyno then came up to me and asked me if I have a MBC installed and if bought this car brand new or used. I told him that I never installed MBC and I bought the car used back in February. When I asked him what is the problem he said that boost only goes up to 20 lbs. and then it drops. I only have few mods on the car:
UR down pipe
UR Hi flow cat
Magnaflow cat back
K&N drop in
UR upper IC pipe
Evo X IC
Evo X lower IC pipe
StageII Cobb 93 octane.
With all this mods John was only able to tune my car so it reached 276 TQ and 237 HP. I know that John from Akuma is probably one of the best tuners in the country. So the only option is there is something wrong with my car.
Suggestions please

Is there an upgraded boost pill? The lack of one (EDIT: the stock one) might make it difficult to reach 20psi. IIRC the stock boost pill at 100% WGDC was like 18-20 psi?
One guess as to who would know best :enterstageleft: lol

Sorry, let me rephrase, that came out wrong. Not that the pill is missing, but that the stock pill has not been upgraded. Or better yet, put in a 3-port and then you know for sure.

100% WGDC means maxed out. Check old posts from razorlab to see what stock RA did for boost when tuned.
EDIT: just checked, 18.5psi. so your higher flowing exhaust is helping but sounds like you need either A) new boost pill or B) 3-port

Confirmed! With AP stage 2 and stock pill I was running right at 20lbs max, when I switched it to the AMS boost pill, and got a new tune, I started running 27lbs max. BTW, that was when I still had the stock RA turbo.
