underboost code, forge or turbosmart diverters?

blackbeast06 · 06-06-2013, 05:15 PM

So I slapped on the new ETS 5" intercooler and ER charge pipe. Filled her up with some E85 and under WOT got the under boost code. I am now going to buy diverters because I think the leak may be coming from the stock valves. After installing the IC and CP I made sure all clamps were tight so I would not get a boost leak that is why I believe that it is the diverters. I will post the log as it shows I am not reaching my target. Is it possible to tell by the log if the leak is from the diverters (I mean is there a pattern of a diverter leak as the boost tapers down?). And also has anyone had experience with turbosmart diverters? Thanks

csvs are usually better to upload than just a screen shot.

I have forge DV's, install was super simple, fit perfectly, and no complaints.

But I wonder if you're underboosting because your trims are so maxed out. Car refuses to run more boost because it can't deliver enough fuel.

I'd email your csv to terry and see what he says.
