Finished SC install -- Can someone look to see if safe to drive/continue logging?

Evening All,

Just finished install of Innovate 210 non-intercooled supercharger with 75mm pulley. Tuned by Mike @ moto-east. 93 pump gas. Car seemed to start fine after tuning, although idle RPM never seemed to dip below ~900 rpm, even after a few minutes.

I took it for my first drive and logged data, staying conservative and listening/feeling for issues. Can someone take a look at this log and let me know if they can see any big red flags? I want to datalog more for Mike, but don't want to be out on the road if there are major issues (i'm new to tuning):

First impressions were confusing -- The car seems unresponsive to throttle input (can hardly rev match on downshifts), and it seems like I have to push down fairly far to get throttle input -- Perhaps this is just due to the tune learning? The car seems down on power as well, but that may be due to throttle input.

Thanks All -- If things look OK then I'll continue driving lightly and gathering data logs. :D

The accelerator pedal has to re-learn after a reflash/ecu reset.

You can make it learn faster by turning the key to the "ON" position and fully depressing/releasing the accelerator 10 times. I find that the pedal is much more responsive and feels normal a lot quicker. Otherwise its a few days of dead pedal for the first bit of travel.

I'm no expert tuner but the log looks ok. Short term fuel trims are doing their thing, there is no knock, and when you are gently accelerating it has no problem pulling a bit of fuel to keep it happy at the target afr. Was this a supplied conservative tune? Seems like its happy enough to supply initial datalogs

Thanks! Yes -- it's an initial tune from Mike. I sent him an email a few days ago asking what figures he wanted me to log (and what styles of driving) but haven't heard back. I figure that i'll record a minute long log of warm idle, highway cruise, medium pull 2nd-4th and wait to see if he wants to see a hard WOT pull.
