I have been told 42#ers for my set up which is only 6 psi ad the mods in my sig. This seems high wat should I go with ? And also can any mass air be recalibrated with a dyno ? Or do I have to match the injectorrs with the maffs calibration?

if you are going to get it tuned professionally , might as well get the 42s , if the tuner is any good , it wont matter

[blakehunter316]

Hmm might as well? Any one else I need a solid answer. And ALS wat a out mac calibration

[flamestang]

I would get the 42# injectors they can be tuned for what you got.I'm sure your MAF needs to be matched for them. You can get a calibration control from Anderson ford performance or by a new one.unless you have some sort of stand alone pcm.

wat is a lightning mass air calibrated too

Lucky for you I just bought 42lbers and I'm looking for a maf as of right now.

You can get a pmas maf calibrated for the blower and 43lb injectors, but you can't recailbrate it on your own.

c and l makes good mafs but their to expensive and small.

What Im doing is either a lightning or 2003 cobra maf. You don't calibrate it, it gets tunes. So get your injectors then get a maf on ebay for under 100 dollars. Your going to need to more things

a plug adapter. Your maf is 4 prong the lightning is 5. The connector is on ebay for 39 bucks

then the adpater to put a pipe on it 44 dollars on ebaqy. Get to work.

a lightning MAF is not calibrated to any injector , and the mafs that are calibrated to injector sizes are much good once you get over a 24 or 30lbs injector

the lightning maf and 42lbs injectors are a popular setup because that is what the lightning trucks had which were factory supercharged , so its easy for a tuner to get a baseline tune done on the vehicle using the stock info from those trucks , calibrated mafs throw off the load tables so they are really a headache in a boosted application ........

these questions you are asking you should be asking the guys whos going to tune it , not the guys on here .....IMO talk to your tuner and find out what he is more comfortable using .....is this a solid enough answer ?

I had said might as well , because you seemed like you were already looking to buy them , you are going to end up needing a tune unless you just want it to drive like crap so if you get it tuned going a little oversized with the 42s will only give you more room to grow later

+1 on the 42# injectors. Spend the money and buy a real MAF like an SCT or C&L and a good CAI to house it in the fenderwell where it won't get any wash from your fan/alternator. You'll also need an SCT or similar device to piggyback on your EEC and hold your tune(s) as well.

I'm getting it dyno tuned march 14th. I know I need it tuned. Just trying to figure out all the stuff I need for the tune. I'm in highschool money is like super tight so I'm not trying to cut corners but just trying to get it done right for best deal possibl.

eBay Motors: 90mm Lightning MAF Air Filter Adapter Flanged Flange 4" (item 360100616017 end time Mar-21-09 18:50:34 PDT)

then you need to buy a maf adapter. The plug for your maf is differn't from that of the lightnings. idk about the pipes. I suppose it will work?
