need help with set-up

[1bad91tsi]

I have a 91 awd a/t talon in great condition.Ive opened up the airbox and have a mbc on it.Also took out the cat and am running a dtm muffler.I still have the stock 13g and it has no shaft play so im going to run it for now.I have upgraded the ecu and injectors to m/t ones.I left the a/t fpr alone.My question is what would be a good boost to leave it at.I havent heard any knock but i dont have a logger either.Would 19psi be to much for this on 93?

Also is there a cheap mod to moniter knock?(led?)

As far as factory fuel system goes you're about limited to 14psi. Pushing it past there is asking for trouble. You also need to take care of that pesky fuel cut problem. With a fuel system upgrade. IE walbro 255 and some 650 injectors and some way to compensate for the increased fuel then sure 19psi would be cool. However, I don't know much about the 13g but you're probably gettin close to the point of ineffecient boost ie just blowin hot air.

Invest in a logger before you mess with the boost...
