has anyone used these with good luck? I hear they are a pain to tune because of no info, has anyone found good info for these at all ?

 

Mine have been working good for about 2 years now. It was hard starting and took a minute to idle right after 10 mail order tune I started with for a "get to the tuner" tune. After I got a good dyno/street tune it starts like stock, and never has a problem ever.

 

Ive always heard as long as you get the flow matched injectors WITH the data there should be no problem. Thats what I have and im hoping for no issues either.
