HELP - Can't get off the line at the drag strip

As the title suggests, I cannot seem to get off the line on the 1/4 mile track. On a normal track when the race starts, I rev the engine and I get wheel spin and off I go. On the drag strip, I do the same thing and on go, the RPM’s drop and it is a good 4 seconds before I really get going. I have all assists off and use manual w/ clutch. I have several top 1000 track times, so I feel like I am a solid driver, but I feel like an idiot for not being able to get off the line here. What am I doing wrong?

you have your 1st gear too long

I will give that a shot tonight when I get home. Thanks for the tip. I should have figured that tuning for Drag racing would be quite different. I was just trying to jump in there and run some qtr mile times for comparison. I will make some adjustments and try again.

when you use manual w/ clutch you have to hold the clutch in off the line had the same problem after one of the updates so when you are reving hold clutch
