Tazer/burnbox will not cut any power when it goes to street mode. It effects the shifting and suspension. I ran the same time when I didn't change it back after a burnout. It's is one more thing to do but once you do it a few times it becomes habit after your burnout. My line lock out weighs the one extra step. @jonx96 was at the track a few weeks ago without line lock and it effected almost every pass not getting a good burnout in

Here are some high 9 sec times slips. This will give you a look at the mph necessary to run high 9 sec et’s This was done on a well prepped track and I was running 3.09 gears with the 17” 315’s at that time. DA777280-DB3B-4999-A3A7-5185E05B6DD2.jpeg

How's the prep? I watched a little of the street car shootout or takeover and they were basically no prep racing. Prep was horrible.

time slips will help to look into further. Is your car really heavy? We all weigh in the same area but have seen some cars pushing 5k. Are you sure the diff is working correctly? Some have said the clutches are worn are not holding well so one tire may be spinning some

2.5 pulley is slowing you down I bet. Many have tested and below 2.75 it gets too hot. Your coolant tank may help but I'd be curious what IATs are like.

I can try a fluid change. And see what the old fluid looks like. Its about a year old.

If you think it is working fine then I'm sure it is. Just throwing ideas out. Have you sent Jon a datalog of a pass at the track? Something maybe happening on launch

I uploaded a second gear launch tune and a soft launch tune. Can try softer but on your tire you shouldn’t be having issue
