It felt like huge turbo lag, which we know isn't the case with a stock turbo B58, but you could see even the RPMs weren't going up like they should vs the peddle position. This would occur even in sport modes. It was a huge hesitation and would make for a very awkward take off because I would just keep pushing the gas further down until it would finally move, but it would be an over acceleration then at that point.

This wouldn't happen as bad in say Eco Pro mode though because there was already a big delay in the peddle anyways in that mode. It was less jerky, but still a slower take off, which wasn't what I was wanting.

Once I got the xHP transmission tune, it fixed a lot of that and now the only hesitation I notice in sport mode, is the actual turbo lag when I'm lower in the RPMs, which is pretty small on a stock B58.

So, I could be wrong, but I don't believe your throttle response units would change that fact much at least on the M40i.

Just a heads up too, the Pedal Commander is not going to change your shift points. You just happen to be accelerating more with less throttle input and getting to your shift points faster during partial throttle, but that's it. They aren't going to change your shift points or make you faster in any way. It's the same speeds you were going before, just requires [...]
Sound like you know what you’re talking about .
Not sure why you are asking questions when you already have the answers .
The throttle response units do remove that lag as it’s tricking the electronics .
Have you tried one ?
