if you get a tune your stock injectors should be able to hold out... but it wouldn't hurt to step up to some high 20's low 30 pound injectors

With the stage 2 if I'm not mistaken you will have to get new injectors to compensate for all the added air thats commin in now. I may be wrong, but I would play it safe and get the injectors.

They're #39's off of the cobra. But i really don't think you need to go that high.

o tru, i always forget if cobras have 39 or 42s

the only reason im getting those instaed of say 30# injectors is cuz i can get slightly used 39# off a cobra for about $125 where as brand new injectoras would be $250-350. unfortunately cuz of my accident several weeks ago, im now on a tight budget to fit the whole hci setup in
