Re: aem tru boost

works great once you get it figured out. With a 9 lb wg spring I have mine set a a67 to get 18 psi. It stays within 2 psi or so for me. Good luck with it!

Re: aem tru boost

Make sure your wastegate works very well. My stock setup with the truboost barely stays safe in the off setting. Any positive duty cycle works awesome but boost spikes to the moon. Next mod on my list is to unshroud the wastegate.

Re: aem tru boost

i have a slightly bigger turbo. and it is all over with the boost. stock gate at 8. one time u hit it its at 10 then goes to 13 as you get to redline . next time hits 12 early then goes to 15 and cuts out. just want it to be consistent

not sure what unshrouding the wastegate is is that porting the waste gate hole

I'm referring to the stock turbo. The exhaust outlet has the piece welded onto it. that piece covers the internal wastegate hole. So in syty factory form, as the wastegate opens, the exhaust gas hits a wall and is forced to make a 90° turn then another 90° turn into the downpipe. In pure stock form, the turbo barely has enough flow to manage boost. By cutting out that wall, and modifying the downpipe to accomodate this modification, you eliminate the wastegate "bottleneck" and allow it to flow freely which diverts the exhaust gas away from the turbine and slows the spool speed that is basically, your boost.

Re: aem tru boost

MY AEM Tru boost works perfect,rock steady boost control.

If I set it to run 20 PSI, it stays @ 20 PSI, no fluctuations @ all.:tup:

Stock wastegate configuration, TDO6H -20G turbo w/a 60-1 compressor wheel mild ported wastgate flapper hole w/a 12 CM turbine housing.
