Hi,
i am driving a Celica GTS with ZEX Nitrous injection system.
I installed the kit this week, but i think i still have some questions about it.
Can anybody tell me his own experiences with nitrous in the GTS.
Here in Germany this kind of tuning is not very popular, so i need help from some US guys.

Please contact me directly with my email, because i will not check this site very often.

the questions i have about the kit:
After i installed the kit i was surprised that power is not so high as expected. I installed the large injection nozzles, but i think i still do not have more than 240 hp. Is this normal with the GTS?
Can i install a second NOS System or is it dangerous?

i am running the 75 shot now, i think i have only about 30 hp extra.

I reinstalled the small 55 shot today and tried a run on our test track.
Without activating the Nitrous i can speed up to 98 miles to the checkpoint.
With NOS i manage to run up to 105 mph.
Not a big difference, but still a little faster!
But it never will give 55 hp as written in the manual!
