No idea about your timing chain problem, but here are a couple tips for basic :P
Keep a low profile, there were kids in my flight that at the end of 6th week the TI still had no idea who they were. Be that kid.
Wear some normal civillian clothes, dont come in with ridiculous hair. I went in wearing blue jeans, a white t-shirt and I had bleached hair... got called trainee Slim Shady for 6 weeks lol ><
Try to get an out of the way job during cleanup. I had pad crew, sweeping where you form up in the mornings. It was awesome, it was like 15 mins of alone time each day :P
Well thats all I can think of at the moment, hope it helps ya. GL
BTW, what job did you get?
