bosst problem.(i think)
i have a 98 eclipse gst 5spd and i just installed RRE piping. well at least the lower and the throttle body elbow piece. they screwed up the upper ic piece. so i have to send it back. but is like a 2psi drop over rpm range normal? like from 12psi to 10? and i havea turbo xs mbc with fine tune. if i try and tune it a little will it elimate that?. or is that always going to be like that?

If the turbo cant hold the flow then it will taper off, or if you have a boost leak it will taper off. Seeing how you just added IC pipes I going to jump out and say get a boost leak tester or make one and it should tell you where your problem is coming from

ok thank you. im going to make one tomorrow morning and get everything ready to do it tomorrow afternoon. before i but the piping on i could hold 12psi no problem and no taper off at a certain rpm either.

ok i just took it out and see what rpm exactly it was falling at. about 5900rpm is when it drops. if i put it in 5th and let it full spool to 12psi itll hold it. i held it for like 10-15sec and no drop what so ever. only at high rpm it seems to drop. and i know the max hp rpm is 6k from what i have heard. any ideas? sound like a boost leak? or something else? anything helps guys

could just be the crappy stock BOV. I would start there because they always leak
