Engine Light Flashing & Dyno Sheet Question

[baby34]

Hi,

Just got my car back from chasers & got an awesome 207rwkw with basic mods / stock turbo

And just wondering when i floor it in lets say, second gear & the engine lights starts flashing for a bit? what does this mean? The guy at chasers is a pretty safe tuner as i've been told..

Also, I got my dyno sheet, and my boost starts @ 14psi then it drops to about 10~psi..

Why is this? Ppl are saying its the actuator, but i think it could be my Manual Boost Ctrller?

Thanks
