Performance Chips

[Alkasquawlik]

I have the stock injectors too and just bought the 91 level chip that coincided with that, so I personally have no reference to it. I have a friend who switched his injectors though and he said it made a huge difference. Like I said, its through word of mouth. Hopefully someone who has experienced it first hand will chime in and can tell you.

I run a stock m20. should I keep the 14#injectors or would I gain more performance if I switch to the 19#injectors?

I was wondering the same thing. I think I might go ahead and get the 19 pound injectors because to do any significant engine upgrades you need to be running larger injectors.

There is no advantage in using the 19lb ones, the stock injectors can handle the majority of bolt ons that get done.......

OK well would the 19 pound injectors and a chip make a very significant gain in performance or would I be just as well running stock injectors and a chip.

is a mark d 91 octane chip a direct plug and play for a 88 325ix?

if you get the chip for that model, then yes. its simple. search for install write ups and follow the instructions. its really easy and takes less than 30 minutes.
