Hey there,
I'm trying to fine-tune my Solstice GXP (5 speed) with the following mods ;
Z54 Turbo w/ Werks WR-EG Turbine housing
#82 Valve springs
Turbosmart External Wastegate
Werks charge pipes
Werks air intake
GM 3 Bar MAP sensors
ZZP downpipe
Solo 3" Street Race exhaust
Fidanza lightweight flywheel + clutch
Note that it's on 91 octane.
Turbo was installed recently. Had some issue with a Cloyes timing chain guide breaking off last week, but just got back to setting the tune for the new turbo.
I'm trying to aim for 24psi. Going slowly because I don't want to overboost.
I managed to get there but I seem to only be able to get that boost, or close, above 4500 rpm.
It feels like the boost should be "there" between 3500-4000 rpm, so I feel like there's something missing somewhere in my calibration.
My issue now is, given how I modify the tables, specially WGDC or the Duty Cycle Correction tables, the boost will go higher than 24-25 psi.
Would any LNF Guru's be kind to give me feedback on my tune ?
Here are two logs I took today, nothing extravagant as I was trying to see if the new timing set would last more than 1 pull.
19juin 1.hpl
19 juin 2.hpl
I have also attached the tune revision to match those logs.
