I know this question must have been asked a million times, but is still unclear to me, I will appreciate if you can clarify it for me, as I am quite new with the scooby.
I have sti02 and I put boost at 1.4 bar with the avcr(apexi), I also have full exhaust and equal lenght headers, but still boost in 3rd gear drops to 1.1 after 6000rpm, and first and second gears dont reach 1.4.
What I would like to understand is if we have to live with this boost drop or there are ways to get rid of it?Like changing turbo?or is that the engine just cant give enough load?
This is the big question: WHAT DO I HAVE TO DO TO GET THE SAME BOOST IN EACH GEAR AND WITH NO DROP AFTER CERTAIN RPM?

 

Anybody willing to answer?

 

up the boost duty on your avcr in the gears which are not making full boost, tells you how to in manual or take it someone like andy f.

 

you'd be better off getting it remaped.

 

I already took care of the avcr, do you think that remapping will solve the proslem?is it really possible to get high boost even in first and second gear or I need a bigger turbo?

 

i have an 05 sti so turbo is a vf35 and with remap it's set to 1.4 bar to peak at 1.5bar and it does as set in every gear.

you could always get in touch with a few mappers see what they think like andy f

 

Yes, maybe has to do with the timing too, you use ecutek?

 

yes its ecutek remap by andy f so more than boost gets changed etc. if you want to get intouch with him heres a link with his contact details http://andyforrestperformance.co.uk/27344.html
he deals with apexi too so will be able to advise you more.

 

Thanks.
