So I'm installing bigger injectors before I get my car tuned, an was just wondeing if I should install them at my house or at the shop.
My question is, will the bigger injectors make me run rich without the tune yet. I dont really want to drive for 30 mins with my engine running rich..

 

yes, larger injectors without a tune will make your engine run rich because the car has no idea that the injectors are larger, so it will inadvertantly sending more fuel than necessary for the engine.

 

thanks, I'll just throw them in at the shop. I figures maybe the ecu would lean em back or something. Oh well haha

 

You would be surprised, i installed the 550's and the car ran decent of course I just drove it around the block slowly and on/off the trailer but it worked ok. Make sure to grab new seals if yours are in question and some long q-tips can help to clean the gunk out when you pull the original ones. Last thing you want to be doing at the tuners is spending a bunch of time messing with the box!
