Hello everybody,
I have a car 335i E90 {N55 PWG}.
A car has a boost leak (I am going to add `datazap` log (I logged this, from the 4th gear), and if someone has a time please review it. I am interesting in, how critical is this loss of power). In the log, sometimes difference between `boost bar` and `boost target bar` is a 10PSI and even more. Is this a crucial ? Firstable, I thought that `chargepipe` has a problem, but now it seems that `intake manifold` has a problems as well. On the car, there are aftermarket DP, CP, BOV, Intake, spark plugs, ignition coils, TIC pipe, etc (Stock turbo/Stock pumps). This moment, I am using {MHD stage2+} and {XHP stage3}.
---------------------------------------------------------------------
When I read about N55, people was talking, that N55 starts losing power ~ after 5500RPM, but my car doing this way earlier (This is visible in the log).
XHP tries to hit redline and when I do manual shifting I got the better results (Almost 1 seconds less, during 100-200 acceleration).
Currently, my strategy of shifting:
1 gear -> shift on 7000RPM
2 gear -> shift on 6900RPM
3 gear -> shift on (5500-5700RPM)
4 gear -> shift on (5500-5700RPM)
5 gear -> shift on (5500-5700RPM)
But in the 3/4/5 gears, a car has way better boost on 4900/5000RPM, maybe better to shift even earlier ? For example on 5000RPM instead of 5700 ?
How is your opinion ?
Thanks !
