hello just had a malone tune stage 1.5 done... few questions i had maybe one can help... new plugs running super 75 000 km

car was slightly hesitating around 3k before the tune, by this i mean pulling then pulling little less than pulling again. this has decrease bah 90% id say... is it due to tuning or is it something else that could be causing this problem?

whats the max pressure the stock turbo can be run at?

i guess im more used to fuel usual fuel injected cars, this one kinda looked stange when i looked at ignition timing, it drops almost to 0 when the car is floored, i presume this is normal? i was expecting it to be in the 20ies and only dropping if the motor was knocking...

i guess checks i could be making is looking with vcds and checking theres no knocking?

what else should i look at while it's pulled ouT?

thanks for your help, im new to this
