20 psi on stock 4g63t ?

[way2fastalon]

ok been getting used to the laser for the last few weeks with the big 16g on there and i cranked it up and some how im hitting 20 psi im normally running 15-16 psi I am not getting fuel cut ... except when the check engine light comes on and then stays on untill i reset the computer im running 92 + octane boost would like to know whats causeing the light to come on

as far as i know the car still has 450 they are blue top injectors i dont know whats been done to the head but i know this i get loose traction when i get in to boost in 2nd gear then rockets to 90-100 all i hear is air moving
... i just turned it down to 16psi tonight affter running around
i dont know if any of u guys were out at sun foods and see it ...

is my boost gage lying to me ? i thought its not possible to push 20psi on a stock fuel system i allso think my 02 senor is bad i run really ritch i can smell fuel when im at a stop but ritch is better than lean ... id run a wideband if i could to see what im acutllay running
