the other day i got on my gsr and it just fell on its face at about 4500 rpm, its boosted to 10psi ,tuned and everything, ran great til now. now at idle it drops way down then back up to 750 then way down, now when i get on it it just slows down after 4500 rpms, then when i got out of it i noticed an egg smell, so would my cat be the cause of all this? searched thanks oh and my gas mileage went to **** too about 200 miles to the tank and the exhaust got alot louder

do u still get boost untill 4500? maybe an air leak somewhere?

 

boost gauge reads boost, did a boost leak check and a vacuum check, all came out good
