BLACKWING & CORSA INDY
<strong> hi all new member just installed blackwing air filter and corsa ex. Do I need to have the onbord comp. adjusted? Thanks for any advise. </strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">Nope. It will do the adjusting for you. There really isn't much of a difference in what you did so the PCM will make the minor adjustments.
<strong> it seems to me to be the natrual mod. Breath in Breath out and $1200 later i expect some H.P. gain </strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">You'll get a HP gain you just don't have to have the car tuned. If you want to you can. But of course, that will cost you some more cash.
