Slow boost buildup? New Pure600's

rhzo10 · 06-28-2021, 12:06 PM

Could anybody take a look at my log? Got these pure 600's installed two weeks ago, however I am noticing slow boost buildup as I am way off target. No boost related codes and brand new boost solenoids installed. Would really appreciate any feedback/recommendations.

Have you been custom tuned since install or is this OTS map?

I'm no expert, just to be clear.

I assume you've done the vacuum lines, checked cannisters, charge pipe and FMIC connections?

Your HPFP is dropping well below 1500psi at one point as well.

Have the wastegates on the turbos been checked properly?

Usually it's really laggy like that when wastegate rattle fix is applied on stock turbos, not seen this much lag on new twins before.

Also have you asked your tuner?

I hope this is not an ots map...

This is on a custom tune, not trying to bother my tuner with dumb questions as I am a complete noob to reading logs. Just wanted some feedback from you guys

It's curious to me that your WGDC drops off when you're not even close to target. It looks like a combination of a boost/vacuum leak and a lazy tune to me.

Have you checked all of the vacuum lines? My Pure 600's spool stupid quick, and i'm still on MHD stage 2+ waiting on a custom tune.

Mate, a tuner is supposed to point you in the right direction, if there are non map related problem's, if he can't be bothered, that's terrible customer service.

If it's map related, his job is to fix it with as many iterations as needed.

You have a boost leak. Your wastegates are closed and your boost still builds slow.

This right here! If you don't "bother" your tuner....how is he going to know that your tune needs adjusted? And if your tuner isn't trying his hardest to make you happy with how your car is running....find a new tuner.
