96 ek with a gsr|||| Guys a friend of mine has a iab control problem. Its not opening all 8 just 4. can he remove the butterflys to get all sufficient amounts of air or will he lose power.

Also will a p28 ecu read his knock sensor on his gsr or do p28s not look for them and allow him to bypass putting it on.

thanks in advance

 

i believe if you remove butterflies, you may lose some low end power. Not sure tho...And if you get a chipped p28, you can pretty much chip it how ever you want it....

 

yeah can anyone confirm?

 

try a search, i know its been covered many times

 

removing butterflies does kill some low end power when you floor it since they open at WOT instead of a certain rpm. It does not affect top end. The p28 does not look for knock sensor.
