"Well i have some new tricks up my sleeve!! I am currently in the middle of helping in the development of Nissdata. simply put it is programamble engine management for Nissans that works just like Hondata. With the system installed the car made 409 Hp / 332 Tq as compared to my previous bests wiht the exact same setup 382 Hp / 305 Tq. This is was doen aat 21.3 psi on 93 octane pump gas on a bone stock block and head, including stock headgasket. Fuel curves are very smooth.
