New to tuning need help or advise on where I'm going wrong

To anyone who knows what there doing I NEED help

I’ve decided the other day to try tuning cars for the first time and for a first timer I think I’ve done ok but I’m not sure if I’m saying this because there mine or if they are lol

I’ve done three of the v8 cars in this weeks league lobby’s the Vf commerdor, the merc and the ford felcon both wet and a dry version

If anyone could download and try it on a track and give me some feed back I would be very great full

My gamer tag is shadeyspade1

The merc I believe is well done I’ve been find hung in top 7 all night but the Vf drives like a old lambo lots of grip then it rips your face off …
