: X5 4.4 with Dinan mods MISBEHAVING!

Whassup boyz and girls.
My second post on the Bimmerfest forum.

I just installed several Dinan mods on my 06 X5 4.4. Got the Cold Air Intake, full flow throttle body, new dual exhausts and Stage 3 engine software. Fairly noticeable increase in both power and noise.
But if I'm pulling into the highway from a lot on the side of the road and I gun the accelerator, the vehicle lurches, then stops, lurches, then stops, lurches then stops!
I've tried it twice: once in Sport mode and once in Steptronic. Same result every time. It's as if the transmission doesn't like the fact that I'm steering onto the road and accelerating at the same time. If I gun the gas on a straightaway it's not a problem, only when I gun and steer at the same time. Any comments and insight would be greatly appreciated.

I'll post pics later.

unless that would be you.:) My Dinan stuff was done by BMW dealer.
I would also try x5world.com; you'll get more responses there.

Good Luck

No, I wasn't the installer, it was an authorized Dinan dealer here in NJ. Here are a couple of pics. I'll check out X5world.com also.
