so my friend and I have both have cirtix stock club race esc's, we are both running about 3.2-3.3 fdr on 21.5 in our 4wd onroad sedans. His car is shaft driven, mine is belt. His brakes are not working as good as mine... We use the program card, and my 50% braking is as strong as his 100%. Any ideas? even going to a higher fdr did not help much for him. his Esc is BRAND NEW...
