Default Injection is nice, but i'd rather be blown

Ok well, this post doesn't have anything to do with blowers... Sorry. Actually I was told I was losing a lot of power with my current set up because of the stock maf and injectors. Do the 24lb. injectors really make that big of a difference? Is it worth my while to buy them and the matching maf?? Say possibly a 75mm ProFlow or something of the sort.

injectors don't need to be replaced untill they are close to being maxed out... you'll know when they are if you get a tunner, or when if starts running lean (at WOT) and you can't fix it...how ever if the car had a poor or stock tune then upgrading to a better maf would help because it helps the computers tune a little

you dont need injectors but your loosing hp by keeping the stock maf. the stock maf is small and doesnt flow very well

Well, you still need to keep an eye on a/f ratio and duty cycle of the injector, a near max duty cycle can cause a serious lean issue in a hurry. I'd say the current 19lbs is fine for your setup, if you do a full h/c/i swap then you'll want to upgrade to 24's or larger and bring the duty cycle down a bit, then in the future if you go forced induction your all set to handle it. A 76mm C&L would be ideal, its the most tuner friendly and can handle 42 lb injector sample tubes. Also did you delete EGR or has that been enlarged to match the TB, thats another bottle neck you may need/want to address. Good luck

your current injectors are fine

you don't need 24's til you break 300 mark pretty good. like 325 you should look to bump

Thanks for your help guys. Guess I'll look into a Pro-M maf.

I suggest you find out for yourself how much HP your setup can achieve. I had 24lbs injectors, and had a estimated 350HP. It would lean out. I was told by a friend that around 350HP is the limit for 24lbs inj. Find out first how much HP you want to achieve.Then purchase accordingly. Goodluck.
