Just ordered some Vemon 720's yesterday. I'm relieved to see that it's not the injectors causing your problem as I was sweating bullets at the beginning of this thread.

And I'm hoping it's not the 1.7 mod as I had planned on getting this soon.

I spoke with Digital Tuning today and they definitely stand behind their product. They are sending me a loaner Rtek 1.7 ECU to determine if the ECU is actually the problem. Hopefull when I recieve it next week I will know if it is the root of the problem or if I have to keep searchng for the gremlin. I will keep you guys posted.
