There are many different "free mods" for the TT Supra. I will mention a few of them. Those who will cover fall into three categories, Boost controller, EGR disabling, and TTC or True Twin Conversion.
Three of the bikesControl mods are: Bleeder-T Mod, Mod Clamp, and VSV Bypass Mod. Each of these changes without increasing the level of promotion of the use of a controller boost. But you have to keep an eye on your boost gauge, and ensures that it will be to increase too high (18psi Turbo) is a measure of security.
The mod, which are the twins conversion mods (or TTC). This change disables the operation of sequential twin-turbo, the turbo and runs continuously, in parallel (both at the sameTime). This system should be a bit "more mid-range power (before the secondary turbo would normally allow online) and smooth power range, without causing additional impetus by the transition from primary to secondary operation.
However, this means not significantly reduce low-end -mod performance, and ... more.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
