John glad you got a pass in ,some days it can be quite hard to fit into the bracket races especially when its hot on the bright side you don't have to wear alot of safety gear
sounds like you did a good job with the car as for a tip get your wife to video the car leaving the starting line ,but only focus on the rear tires ,on the race track it has so much traction built into it is almost impossible to detect tire spin from the drivers seat , so either a video or a partner on the line watching is the only way to see
as for the burnout people don't realize how much practice goes into making a proper burnout for your car the problem is the only true place to get practice is at the track because of the amount of rubber on the track (find a street or parking lot with that much rubber and I'll be over for some test hits
)here's a small clip of one I did when the temp was hot and it was the first pass of the day granted are cars are different ,but you can see how fast and smooth I go thru the procedure THIS IS NOT ROCKET SCIENCE it just takes seat time

as for the unstability on the top end check your alingement make sure all tires are balaned and MAKE SURE ALL BOLTS are tight everywhere each week before heading to the track adjust your steering box so that it is tight no slop on the steering wheel then back it off to about a inch or two of slop each way the biggest and most comon problem people get thierselves into is over correcting on the top end ..... when you are going 100 mph the last thing you need is to twitch and send the car upside down thru the lights ....so a little slop or slower steering is actually better in a drag car thats just my personal opinon
Keep us posted and we'll keep helping
