Well i just got my car from the dyno and and it was running lean around 5000 rpm at about 11lbs of boost the shop said i needed to upgrade to 60lbs injectors from the 42s i have now. What do I do about a mass airflow sensor? I have a c and l on it now but c and l doesnt make a calibration tube for 60lbs injectors or at least I have never seen it so what do I need to do? 93 mustang 331 stroker with a v-7 y- trim on it
what mass air?

no, you buy the sct, and havve someone tune your car for your injectors, when you are making that kind of power you really need a tune. you must be making a ton of power though, we push the 42's in our lightnings to over 430RWHP out of a 5.4L with 15-16lbs
well i made 480 h.p at 5000 rpm the shop said i would make over 500 if i get some 60lbs injectors, I am really just trying to go the cheap way around this. Because my buddy has some 60lb injectors for me so is there any way i can just get the mass air already calibrated and then get it tuned after

we maxed out the lightning mass airs at around 400hp...
you are trying to make 500hp. let me give you some advice.
here are three words cheap, reliable, fast
you can pick 2.
pony up for an sct, they are like 250 bones.
what block is in your car? if its stock its on borrowed time at that power

Its a stock block and I know they arent suppose to take that much power. If i blow it up ohhh well thats the name of the game 302 blocks are a dime a dozen I dont want to fork over 2000 for a dart plus another 1000 for machine work that takes all the fun out of it. Im just wondering about the cheapest way to do this, this car is strictly a budget build but if any one has any ideas to keep it cheap im all ears. So I guessing the lighting mass air wont work.

You will definately peg a lightning maf. You could leave well enough alone or spend the cheese and get 60 lb'ers, SCT maf, & tune the car. This is who we get ours from plus he does our tuning. SpeedyDyno.com you can see the link in my sig for his tuning work.

So I take it that it was just a dyno and not a tuner. A tuner can tune the car to what your injectors can do. Meaning they can make it so that you can take the car to the rev limiter and not run lean (de-tune the car a bit).

that sounds like a great idea, instead of spending a few hundred to do it right, lets try to band aid the issue, split the block, trash the crank and spend a fw grand putting it back together...
calm down! If i see her go lean on the wide band I will let out of her. And its going to cost me more than a couple hundred to turn her, after injectors, mass air, chip and tune your looking at $1200 easy. Im sorry im not john force where i can just throw that money around I guess you didnt listen to me when I said BUDGET build.

i know what it costs, this isnt my first go fast rodeo. the sct is a few hundred, and you can find them used for less. you said you already have a hook up on injectors. chip and tune are 500-600 usually. so, for a grand or less you dont have to worry about watching your gauges and going lean.
you're the one who said if you cracked the block you didn't care...
All I am saying is if I can get out of spending $1000 and try and tune her myself. Why not Right? Come on I know you have been in my shoes before when money is tight and you just want to have so fun with the car? Isnt that what they do on the dyno is adjust to a/f ratio I will be doing the same just at the track. I use to do it with nitrous all the time and thats even more hard to predict. Do you think its a bad idea even with a wide band in my face.

If its just car to have fun with, then why going through all the trouble just to get a little more HP out of it? I would be content where you are
We know what you are saying, but you are building a 500+ HP setup and asking for round-about ways to get more power.
The truth is some of the things you want to do may end up costing you more in the long run when it costs you your motor.
At the power level you are at, you should really be getting an SCT and dyno tune anyway. That's a lot of powee to be tossing around on a stock block and hot have a safe reliable tune verified by a dyno tune. Leaning out is going to cause you problems not easily cured by a lightning MAF.
MAF recalibration should be completely forgotten about. This isn't 1992 anymore. It was good when custom chips and tunes were WAAAY too expensive back in the day but now dyno tuning should be the only way to go.
I know your goal is a cheap budget build, but 500+HP and cheap don't really go hand and hand together.
