Default Stage 2 + APR users with boost gauge. How much boost are you seeing....

WOT off the line? Having some funky boost issues and it may just be my gauge, but not ruling out n75 either. 3rd gear pull seem normal, but logs with stops and starts seem to get a little weird with request and actual, particularly in first gear. Just would like comparison.

TIA

Default Thanks, this confirms with my most recent logs that n75 is on fritz.....

As for some reason in 1st gear peak at 10 psi, but everything was normal. No boost leak could be discovered even at 20 psi.

Default interesting. I am Stage 2 + APR, and always thought that less boost in 1st was normal

I figured it just couldn't build boost quickly enough before I hit the top of first.

I show no boost leaks, but typically peak around 10-11 psi in first!

Though- wouldn't there be a CEL of some sort?

Could I log block 115 to test the N75?


Let me know how the fix works out (could you email me when you do?)

Default Normal. The load the ECU sees in 1st is smaller than the load in 3rd gear so the ECU doesn't

request as much boost.

Default YUP! It was not just the first gear issue though completely struggling to hit 14.....

but again pressure yet revealed nothing. I know it is possible there is a deeper leak, but looking at the differeence in log 115 I do think it is n75. For 100 bucks and 20 minute of my time I'll experiment.
