Default stock map sensor and boost.

so with a stock map sensor my understanding is if you boost over 12 psi it will burn out. well my car spiked 17 the other day and now is missing on top end. does this have to do with the fact that its not reading now and not pulling enoug timing under boost ? normal driving is fine

Read the rules. You failed to give us a large amount of required information. We aren't here to play guessing games for you.

Eh, I'll bite

Stock map sensor won't read pressure over 11psi. Yes you can kill the sensing components if you expose them to too much pressure. However if you can't appropriately tune for higher pressure then that spike more than likely damaged more than a map sensor

OP - You most likely blew your engine from being untuned in the region you boosted to. Time to give the engine a full once over. I personally haven't ever fried a stock MAP sensor from boosting over its limit. Ahhh, the FMU days... LOL!

Oh yeah... the V-AFC/ S-AFC / 450cc DSM injector "hack".. Those actually were pretty decent back then if you didn't mind staying in closed-loop. Ran rich as hell, but the **** worked like a charm!
