Ive got your point, but as i said above - dyno numbers means nothing if the car doesnt perform well. MGF st2 OTS tune proved to be powerfull and dragy numbers comfirms that. Also there were some racing against different cars wth good results for MGF st2 OTS.
I'm just curious what the actual before and after dragy numbers were that are being taken as a confirmation of using a specific tune? I've just never heard that rational before so I'm trying to understand. Thanks.
