third gen bogs down

[rx7bug]

i have been having problems with my third gen,
first thing is first the car is stock no mods witht the exception of a down pipe to replace the precat.
the car was down for 2 months while waiting for the pipe.
now that i have the car running it boggs down. when i drive it at a modest pace it is fine but the moment i want to get froggy it will bogg down, it does it in every gear.
feels like i am loosing boost . i know i have an exhaust leak but it was nothing new.i checked all the vacuume lines i found 2 that needed replaced but even that didnt help.
i dont think i have a blown engine since it has great get up and go
im getting a compression check soon so that may give me an idea of what it is,
if any one can give me advice of some thing that i missied i will go ahead and check it other rx7 forums have not helped i hope you guys can help
