car lays over when shifting from 2nd to 3rd during burnout
im using HP tuners it looks like all the TM is turned off but ive noticed that when i shift from 2nd to third during my burnout the car lays over and drops rpms pretty drastically. anything i should be looking for in the tune? setup is a turbo LQ4 based 408 with a FRMVB th400. thanks in advance for any insight.

I do exactly what jake at jakes performance recommends to do with his trannys. Something to do with wheel speed or something like that. Who am i to argue with someone who knows infinitely more than me about my th400? my laptop is being screwy lately. I will post a log asap.

Here is a good explanation
Many a sprag has been broken coming out in 2nd gear. roll through the water in first gear, stop/set your LL and pull into 2nd, wait for the command to start your burnout, get upto rpm desired, pull 3rd so the entire transmission internals are locked together and share the shock when you roll out of the box and tires grab...the only way to do it.

Are you sure it's not just dragging the motor down because it's starting to hook in 3rd gear? As you burn the water off you're probably also shifting into 3rd gear, The tires will start to stick and put a load on the engine and cause it to bog. It doesn't take much power to spin wet tires in 2nd gear but when in 3rd with sticky tires... Your probably just running out of power to keep them turning = Bog

i posted this on facebook and got 10 things to immediately look for mechanically and in the tune. with zero drama or anyone being a smart ***. what you think just because someone sports a 10 year badge or posts alot gives them the right to **** on someones thread or be a complete douche? you may be one to lay down when somebody acts like that but i sure dont.
