Message That is correct. Only the standard upgraded JWT 370cc injector ECU which I installed in 1995. The wet shot of nitrous is rated at 60hp but adds more than that with the cooling effect of the nitrous. This wet system also allows me to push the turbos to their max with stock injectors because of the extra fuel that is delivered through the wet system. The cold nitrous off sets the extra heat that usually would cause the extra PSI to be of no gain when pushing these small turbos to their max. The 11.84 fuel ratio was the leanest I have ever gotten it during a dyno pull. It is usually very rich in the low 10's. I raised the bottle pressure up to 1100 PSI to help lean her out a little. Usually I run it at 950 PSI bottle pressure. Bringing the AF ratio to 11.84 helped me pick up a little HP since my last time on the dyno. TQ numbers have always been over 550, but 584 is the best TQ numbers put down so far.

She has 600 TQ in her, but he started the pull a little late at around 4500 rpm. HP numbers are about all she has at 524 as they usually peak at 5000. TQ with these small turbos and N2O peaks all the way down at 4200. Next time I will get him to roll into it around 3750 to see if I can get 600 TQ on record down to the wheels.
