Title: Boost cut help,
Post by: clive on February 26, 2007, 08:55:22 AM
I have had a member contact us with the problem of boost cut after he has changed his air box to a single filter and removed the cat,

On FD\'s there is a trick to stop this, so my question is.

Are there any tricks he can do other than put the cat back in to "fool" the ECU??

run a FCD - that should help - it will stop the boost cut at .5bar

Not to be a kill joy but if its hitting the Overboost would\'nt it be better to fit a Profect B to try and control the Spike/Creep then you may stand a chance of keeping the Boost in check, i think it would be a better idea to fix the problem rather than take off the Limiter ;)

Out of intrest is it a S4 or S5 T2? i know the S4 had more of a Problem controling the Boost due to the single Button on the waste gate the S5 seemed to work alot better.

I wouldn\'t have de-catted unless I had an Apexi or something to go on it.

Other than that though how about having a restrictor plate made to go betwene the midpipe and cat back?

this is a FC we are talking about

or i assume it is based on being in the 2nd gen section

an apexi in a FC is over kill for just a decat and filter :D
