I currently run a blade style MAF for one of the Cadillacs, cant remember which. But it is operating at or near its limit. Anyone have a recomendation on which MAF to use? I am running the stock computer from a 2005 GMC Sierra, Bosch O2 sensors, and a 4 inch charge pipe.

 

Switching to a different MAF isn't going to change much. You need to increase the size of the intake tube so you don't hit the airflow limits of the MAF.

Or ditch the MAF and go speed density.

 

I'm on the older P01 ECU, but I think the limits are very similar for your 05. I have an LS7 card style MAF in a 4" pipe (probably the same MAF as your Caddy). Which limit are you hitting Hz or airflow? Do you have a scaled tune?

Without scaling the tune, I hit the 4063 lb/hour limit in my ECU around 9 psi on my LQ4. Literally this past weekend I scaled the tune by 2/3rds, so now it can support a little over 6000 lb/hr of real airflow, which should be close to my other ECU limit of 12,000Hz. Doing some rough math, that should be good for 21 psi, which is higher than I want to go on my stock bottom end.

 

I am running speed density on a 4 inch charge pipe now. In the midwest the humid summers and cold winters make idle fun on speed density. How much bigger, 5 inch, 6 od?

 

Do you have scanning software like HPTuners? Do you have a WOT run on max boost with Dynamic Airflow logged? Easy to calculate needed charge pipe size from those numbers if you want to post them up. Otherwise post some details on the engine and amount of boost you are running.

 

Go speed density. I ran a 4” intake with no issues on speed density

 

I don't have the HP tuner but I do have the ODBLinkMX+. I will turn on the logging for air flow, boost and whatnot and make a few pulls. Will post as soon as I can.

 

How much difference do you see with the Wildwood brakes? Worth the price?

 

the brakes are badass. worth it to me but you have to run 20" rims or larger. I wanted to run a drag set-up and that kinda limits what I can run
