I had the car for a few months, the power is great in stock form but felt it was not as smooth as I expected, torque "could" be better, turbo spool up was not as fast or smooth as I wanted. The throttle response also could do with some tweaking.
Tried an OTS tune - which had great reviews but from the dyno seems a bit low on power though the throttle response was great.

These tuners are amazing, the dyno cell used which was fully calibrated indicated the engine to be in good health - ~ 507HP crank.

After a full day tuning on the dyno and street tuning - I am really pleased with this tune and smooth driveability and amazing area under the graph torque.

Not bad for just Fabspeed Xpipe and an intake + customs stage 1 tune. - 561HP and it was pretty hot too. All tuning was done considering high temp, humidity and local 98RON fuel.

Did you leave all hardware stock?

Fantastic - nothing much on the road can touch this or come close to it. Shopping, daily, practical and a bit quick.
 
It looks like it has a boost spike at around 3500, which then drops down again. This should really be tuned out on a custom tune.
 
Don't want to dampen your happiness but with exhaust and intake and tuning (which is considered a stage 2 btw) you should be seeing a 100whp (around 620ps) increase over stock, not a small 52whp increase at the crank.

Even a cobb OTS would give you 50whp without any hardware.

Did you get the car boost leaked checked? Do you change and gap the plugs?

Something is not right.

The tuners said it was stage 1 and needed to be safe so yes it can have more power but the heat and humidity here is not ideal. Stage 2 is with catless and intercooler then yeah the 620hp plus is possible. Plugs are new and so are the coil packed as for boost leaks I will check later at the garage at the next service. Drives well though. Thanks for the advise.
