hey. looking for tips & experiences anyone has had with nos on the ztech focus models.<br><br>thanks,<br>whysyn<br>'02 zx3 liquid grey

I don't have NOS brand i have Nitrious Express (NX) brand on my VW GTI. I didn't have good luck at first. The reason was i started with a 35 hp shot and it wasn't enough. Then, i went to a 75 hp shot. And, my car fouled a plug. Then, it felt like i lost alot of my bottom end torque and hp. But, i found out yesterday that there is a recall on my mass airflow sensor. So, i'm taking it today to find out at the VW dealer. My advice would be to only go with a 50 shot at the most unless you do some internal work. I guess that 75 shot just scared me about blowing up my motor. I am ordering a kit for the Focus too. <br>Girliracer77<br>2002 ZX3<br>2000 VW GTI

You are fine if you stay below 70. That's all
