2015 auto VT, 2013 manual VT × 2
Log looks "normal" for the mods and conditions far as I can tell. A better log with 3rd or 4th gear pulls I can see better data.
Got it. Do you have any recommendations for a good tuner? I've been putting off any power adders for the time being since the engine is so high mileage, but getting rid of some of those power cuts would be greatLooks normal for the oem tune and the mods. If you're having any power cut at times it will either be normal if hitting tune limiters in some parameters at times or abnormal due to fueling, plugs, coils, etc causing issues.
I can easily sort out any tuning issues like power cuts regardless of conditions or driving style up to a point and still keep it safe.Got it. Do you have any recommendations for a good tuner?

Probably is a boost leak, that's the most common problemHello all,
I've got a 2014 VT auto with some weird issues. It seems like I'm down on power, maybe 20-30 horsepower. My gas mileage has gone down as well. This issue has come up recently, but I can't pinpoint an event that would have caused it. I've checked just about everything I know how to check and can't find a clear solution.
premium gas only
air filter cleaned
Reduction from 30-35 MPG to 25-28 on the dash
fluids recently changed
sparkplugs recently replaced
coilpacks original, but all meet resistance spec
ODB2 reads turbo pressure between 15-16PSI maximum
ODB2 reads fuel pressure between 25-35PSI at idle
OBD2 horsepower reads between 145-150
Fuel pump recently replaced with Deatschwerks 65c
ODB2 reads High pressure fuel pump around 1500PSI at idle
Compression test performed, read around 200PSI on all cylinders (one test read 145 on cyl. 1, but could not be reproduced)
Short ram intake, aftermarket turbo hoses, torkpipe, GFB diverter valve, Pierburg Wastegate solenoid, MAC BOV solenoid
As far as I can tell, the air is getting into the engine, the fuel is being delivered at the right pressure, the fuel/air is igniting, and the turbo is compressing within spec, but my brother's veloster that's stock feels like it's pulling way harder. I haven't had a chance to Dyno my car beyond the Torque App horsepower reading. Any suggestions you might have would be appreciated!
