Managed 12.9, 12.8 and 12.6 with a slow 2.2 sec 60 feet. Ute has 319 rwkw. I was told by few to work on 60 ft to get into 11secs.Upgraded rear tyres to et streets. Tried again.Launched It from 3000 rpm with 60 ft at 1.8 sec but then auto refused to change into second gear and started to cut off the engine. I had to throw it into drive. still managed 12.6.second run. 60 ft is 1.9 the auto goes into second gear but then ute started to shake, felt like it was running low on petrol or out of air. Had 3/4 full tank with bp 98 and octane booster.Very strange. When launching at 2200 rpm no problems at all, when launching at 3000 rpm then the ute is unpredictable. Any ideas what can cause this madness? Link to comment https://www.fordxr6turbo.com/forum/topic/87754-shaking-ute/ Share on other sites More sharing options...

How long since the power mods went on? How many kms on the car pre and post mods? I see it's the 4 speed auto, is that box still stock? Slipping trans? Mine didn't shake though it just made the car sluggish, but I have a ZF.Shaking isn't axle tramp is it?

It's not sliping. All mods are about 4-5 years old, including fuel pump. The car was retuned and dynoed couple of weeks ago.It works without any dramas when launched from around 2000 rpm, and it goes into stupid mode when launched harder....
