hmm.. TD05 runs 7 or 10psi stock (depending on whether it's intercooled or not). if it's off an Eclipse, then it's a TD05H. i'm not sure how similar they are to the TD05 (different exhaust housings), but i'm pretty sure it's about the same. as far as i know the TD05 housing is only on Starion/Conquests. TD05H is on DSMs. most likely what you have is a 14B, so you could potentially push prolly around 15psi before it's just blowing hot air.
