oh no! not another sr problem thread

[rps13drfter]

ok so i just read about 2 hours worth of searching the forums to find some things out that could be my problem but none seemed to be the same problems im having.

Engine/Setup: Red sr20det
Greddy RS bov
Apexi Gt Exhaust
no tuning of any kind, running w/ no o2 sensor

Symtoms: i started my car this morning like normal drive it down the main street everything running same as usual as i merged on the highway my car started to hesitate, buck, loss tons of power, looked at my boost to see its was at 1-2 let off and it was as loud as it would be at 8psi. Pull over checked the vacuums, IC pipes couplings nothing found, got back on the highway going much slower (grandma accelerating) no problems untill i give it that lil bit of gas then all symtoms come back. Seems like im running super rich as well

Stuff i tried already: Checking my spark plugs to find white residue on all four no black, going outside right now to check the maf/tps/coilpack


If anyone had these exact same problems and fixed please let me know or just anything i might be missing to check.
