All depends on the engine.....
T34 is perfect for a monster such as Wuls
I ran the Stage 2 T3 after talking to Turbo Technics, i was hesistant as i had been there.
Overall it was great, brill at picking speed up out of corners but for me i felt it was just lacking at the top end a bit
I have upgraded to a TT Stage 3 T3 and that seems spot on for a nice alrounder
In the past i ran a 4X4 Cosworth T3 and i loved that!
