I recently had my car dyno tuned so I could install my 3.2 pully, the tuner I used has done many mustangs but this was his first Marauder, I have to bring it back the shift points need alot of work and I need to install a larger MAF I have attached the dyno sheet he said that my stock MAF is pegging I would say he is right due to the stock MAFs rated to 425hp from info on this site, my question is I have a lightning 90mm MAF housing in the garage but not the meter can I buy a stock lightning meter instead of buying the SCT BA2600. saving money is the goal.

You should find an SCT MAF used or a Lightning MAF with a MAFia.

Saving money and owning a supercharger cannot be combined in the same sentence.

A 90 MMLM is good for about 450 you will close to pegging it at about 440, you can buy a Mafia Maf extender, or go with a SCT BA3000 Maf and that is good for a lot more.

Thanks for the answers, I guess I will wait a little longer and spring for the SCT BA-3000, I also want to do the IAT relocation to the lower intake before the next tune.

Check out www.svtperformance (http://www.svtperformance) Under Terminator Parts I saw a used MAF 90mm sensor & housing for a fair price just the other day.

Just buy a new SCT B3000 and be done with it, you will probably need a 4" air cleaner adapter I have both in stock.

Can I ask what other mods are done to your Marauder? I plan on dyno tuning my car in a couple of weeks, and I also have a 3.2" pulley to install. But, I also have a JLT intake and Kooks full exhaust. If you're pegging the MAF right now, I wonder if I'm going to run into the same problem? I'd hate to get on the dyno only to run out of MAF and told to come back for a second time.

I have stock exaust manifolds 2 1/2 inch with Xpipe JLT and that is it, you will need the MAF call Dennis and order the BA3000 and the filter adapter

The stock MAF is good for the 'as shipped' Trilogy Kit.

Anything upgrades will make it necessary for a MAF change or a MAFia

Okay, thanks for the info. Looks like I have some shopping to do...
