I think that car is definitely better but I have only K&N Filter and Perrin 2.5 resonated and 1.59 Stage1. I using European premium gas (Like OMV Maxmotion 100 or Shell V-Power Racing - 100RON). I just want to be sure, that Ill not screw anything .
First looks like my MPG is lower now, is it normal ? Should I expect that with every tune (like stage 1, then stage 2), it will need more fuel and MPG will go lower ? ( Or maybe Im driving it much harder, because I enjoy it more ?)
Second, I have a lot of KC learned values there (0-6.5), but KC Correction is 0.. Is it normal or not ? Could I injure engine ?
Third , also AFR is going under 12 in high RPM. Is it normal too ?

In the zoom, you can see acceleration 1st and 2nd gear up to 7K RPM)
Thank you very much

Generally when people want a tune on a sports car they want more power so thats what tuners aim for and generally more power means more fuel.
I find if you drive smoothly and at lower rpm say below 4000 economy is unchanged from stock tune, but driving agressivly it worse, but better torque and power.
I did a trread on knock correction called KNOCK FIX FOR AUSTRALIAN FUELS but applies to you as well explained knock parameters ect
OFT tunes run a bit rich up top for safety and knock resistance over 6500 you will generally see low 12 or even high elevens. If you have good fuel you could lean it out a bit as long as it remains knock free
