Great let us know how you get on with that. I have no experience with anything like that but I do know how important precise throttle and brake control are.
The thing I've seen most often is people way too eager to get on the throttle both too early and too hard. A friend was getting all depressed that his Megane RS265 was lapping much slower than expected at a trackday and asked me to passenger in the car with him for a few laps. He was brave I'll give him that and we were using all the grip the Megane had and the diff was making some serious moaning noises on the exit of each corner. I've had enough instruction to give a few pointers and using the lap times on the PerformanceBox we could measure the difference. He'd been running anything between 1:19.8 and 1:21.2 laps and the well drive Clio 200 Cups were hanging on to him, hence his displeasure.
Over the next 5 laps he just balanced the throttle more, easing on the power as he unwound the lock while letting the car find it's natural line toward the outer edge of the track. No more strange noises from the diff and almost 10mph gained at the end of the longest straight as a result. Again through a long sweeper where he'd previously been all throttle and a big lairy understeering slide toward the infield he now balanced the throttle. The RS265 will behave remarkably neutrally if you do this, this time both the apex speed is up by 5mph and the brake point for next corner by 8mph. The final corner on this track is true 180 degree wide sweeping hairpin, it's here he had been spinning away most of his speed, with an apex speed of just 23mph because he was back on the throttle way too early. Taking a later, wider line and with the lighteat throttle pressure he got that up to 29mph and removed all the horrible diff and wheelspin noises too.
The result, consistent 1:17.2 laps and the Clio's were eating dust. It was awesome to see the transformation in a few laps. It's hard to believe at first but slower, smoother and more balanced is the key to going faster. So this was my Harry Hogge "Run laps any way you like, then laps like I want you to. Give me an honest run. If you do, I'll beat you.moment" in life. But seriously I only know any of this because I've made the same mistakes.
Anyway to the point, if the pedal box gives you better control and a more linear throttle then it has to be a good thing.
