Has anyone here used them?
I want to make 500cc injectors to 720cc I want to know if thats a big jump (able to do) and do they do pretty good work.

i bought new 550's from them but i dont know how much it is to upgrade those things

[Rotary7]

So have you heard anything about the stock injectors getting bored out?


How was the service..and did you buy NEW injectors?

I need to get bigger secondary injectors <--- Street port

They are supposed to be the best. BUT, having injectors upgraded costs more than what it costs to just buy new ones(I think like $300+). You can get 2 720cc's for $220 new and sell the 550s for like $50 or more.
