250HP Nissan SILEIGHTY VS. 281HP Nissan ALTIMA SER
I'd guess the guage runs off the ECM, if you think that's cool I'd hate to see what you'd do with the new GMs, Tire PSI per tire, Trans temp, Oil temp, Coolant temp. I'd say they are high 1/4s as my GTP Comp G would walk one with just a pulley and tune.
