I've actually used a number of the TLD tunes, and found them all to be an improvement over standard. I typically have difficulty with FR cars, as I have a heavy throttle (thumb), as it were. I can only imagine it would be easier to control the throttle with a wheel/pedal setup, but I digress.
So, limiting this review to the 350z, I drove the car exclusively in the 600PP Suzuka races, and had some good success, notably when there weren't any well-driven Clio's running around. The standard 350z is a fairly well sorted car in its own right, only lacking in umph, in my opinion.
The TLD tune takes an already fine car and allows it to exceed itself. Gearing is spot on, allowing aggressive throttle application with maximum grip. When the tail does step out, it results in beautiful, easily modulated powerslides if that's your preference, or simply adjust and bring the tail right back in line, no drama, no fuss, whatever's your pleasure, sir. TLD has taken a car that may typically be a backmarker against the numerous vehicles that are both lighter and faster, and made it competitive by making it more than the sum of its parts. Excellent work, in my opinion.
I envy Holden his seeming intuitive knowledge of gearing, specifically, I couldn't tune a car to save my life, and often use his gearing choices as a sort of "Tuning Bible", never straying from his obviously tried and true settings. Given my propensity for losing my rear end (no pun intended), I'm appreciative of having him as a resource. I suggest we treat him well, and give him all the kudos he deserves.
I've driven several other TLD tunes, including the Amuse Stook, Z06, Jag, Ferrari 512, M3, and a few others, and found them universally more driveable and faster than their stock counterparts. I hesitate to give most of these cars my review because of my aforementioned inability to modulate the throttle in anything more than an "on/off" position.
Thank you TLD, and keep them coming, you have my enthusiastic support!
I feel like I'm doing something wrong.
