if you're only going to 24# youmust not have a lot done to your car. its really a waste to:

buy injectors $300
buy MAF $150
tune the car $250


you do know that you WILL NOT see a power increase by stepping up to bigger injectors and MAF, right?

Why are you changing injectors , stock injectors on a modular will hold just about every bolt on you can throw on , bigger injectors are only needed for big shots of nitrous or blowers, regardless you will need to get a custom tune to change the injector slopes and the MAF transfer function depending on what MAF you go install , post more about the details of the combo and what MAF you are thinking about getting and why you think you need the 24 lbs injectors and you might get some better advice on what will be the best supporting hardware for your combo .......

you will need a tune, and you really dont need to bother changing the injectors and MAF you are not even close to maxing the stockers out yet.

There ya go man, we just saved you a lot of coin. Spend it on a good tune and ask the tuner to tell you what % of the duty cycle your injectors are at and how close your MAF is to being pegged.

or you could split the $700 in half and send it to me and kilgore for the great advice. i'm sure he could use a little extra cash for some preventative maintance on the kewbra

Nope, I am all set on the PM

I could use it to get a nice custom tune however. I am getting tired of the stall issue and the boost bypass ruining my fun...
