Some tricks to getting the “Squeal like a Chicken” achievement.
The Major Trick, and the Tips
Here is a major trick: First of all, Fletus starts ahead of you – on the other hand there is a slight delay before your car starts moving after green light, while Fletus starts with a burnout almost instantaneously. The tip here is to tap acceleration [W] constantly when the countdown begins, – do this until the countdown ends and instantly hold acceleration and hit boost as soon as the Deuce starts moving. You will have a noticeable head-start.
While racing, try to avoid any sort of impact with the environment (duh), and do NOT try to bump/ram the Squealer, his car can easily knock your Deuce off balance. Just do the first major trick I mentioned, and drive past him while keeping your distance.
Note: These tips can be applied with or without getting all the Deuce upgrades.
