Question AP -18.3 @ wot in 5th and 6th gears

Right after flooring it the boost hits 18.3psi on the AP for a second then tapers off. Is this considered a spike? No abnormal engine noise. Solutions? Thanks.

18.3psi is the max it will read. You should have a boost gauge to see what its really doing.

what stage are you running?
stage1 and 2 on sti suppose to hit 17.5, if its higher or lower by .5 its fine
but in your case, you should run lwg

That seems really high. Did you just reset your ECU? It may be trying to learn and adjust but if not then I'd be careful going WOT with that kind of boost.

Seems a little high....but if you are in 5th or 6th and around 2.5K rpm and flooring it to get around the grandma in front of you on the on ramp...then yeah....you will see that happen. You might want to downshift and try to keep it in the power band

I actually flashed the 93 stg 2 in last friday. I was out test driving and wanted to check the boost levels and have some fun of coarse. So I took it on the hwy and @ 2500-3500 rpms I'd floor it to check for boost spikes and viola! Ap real time boost would shoot to 18.3(I am aware its the highest the AP will read)and quickly taper down. No abn engine noise. I assume the stock ecu will protect the engine if I'm overboosting correct. I mean thats the benefit of reflashing the OEM ECU that you keep the factory ecu protection??? Would you recommend trying lwg93?? Thanks to all who responded.
