850 t5 boost levels
Hi folks, So my 94 850 t5 had been running low boost for a few months and I hadn't got round to sorting it, but recently got stuck in, replaced the TCV with one from a later V70 (the one with all the nipples at right angles to each other) and the boost was then pushing past the white quite a bit (20-21psi maybe?). I thought this looked a little unhealthy, and I was going to swap the turbo anyway so rebuilt a 16T and dropped that in, so new wastegate and blowoff, Also replaced all the vacuum hoses, wore it all in, and she's still pushing what i'd think was pretty high boost, and I'm wondering whether the TCV is unsuitable/a duff? She has a Rica remap from a previous owner, the block is from a later 1999 V70 R. the boost is decently progressive and it's not hitting the high until around 3500 rpm, I'm not getting any fuel cutoff, I'm just wondering if this is safe or should I go and get another TCV from an earlier model? Or is this worth borrowing a boost gauge for to check it's not the OEM one just being innaccurate?
