Normal tune and catless tune are different. Also the catless downpipes will throw a CEL and the ESS catless tune will sort that issue out

Check out the differences on the dyno above.
First one is with stock cats and 95 RON fuel tune
Second one is for catless 95 RON tune
(NOTICE HOW THE CAT-LESS HEADERS ALLOW THE POWER TO GAIN AS MUCH ON THE TOP AS THE MID RANGE FROM STOCK, WHILE THE TUNE WITH OEM HEADERS LOSES THE POWER GAIN RATIO ON HIGHER RPM RANGE)

I haven't dynoed but mine has the Akrapovic rear section which is good for another 10 hp and 15 torque, plus I have tune for 100 RON which I'm sure is good for anther 10 -15 hp also and a shit house full of torque

ESS has tunes for both options as well as different fuel used

I have 2 tunes from ESS:
1. catless 95 RON
2. catless 100 RON fuel
