I too am very close to gold with this tune. I am amazed at how well it handles on SH tyres bearing in mind it is a ACR viper... PD physics defy logic sometimes He is a very fast guy.. Your not wrong there. I have an idea. Practice, practice, practice. I am going to try and make a new transmission for this car based on what we can actually do with it at the moment. Will work on this later/tomorrow and see what I can mangle together.
