Far as i know Chuck is right on that too, but i haven't looked into it much as i know this stock MAF will flow enough air for 850-900 RWHP so no real need anyways. Past that SURE SD tune the car its best!
just cause it has the MAP based tables doesn't mean they go up to 200-300KPA. Ill have to go and look through HPT and see how far up they go. haven't looked in a week or so at the C7 tables.

IMO it's unreliable and I also think foolish to utilize on a high HP boosted application. The only example I can give you is I had a cam/fbo 5th gen Camaro come to me one time that was tuned using the Blue Cat VE generator. The customer was complaining that the car didn't feel like it should. It supposedly made 450 RWHP on this other (very well known) tuners Mustang dyno. But first pull on our Dynojet was a different story. We made 3 pulls w/ the other tuners tune, A/F was spot on, timing was spot on, but car was literally making crazy low numbers. Threw my tune in which bypassed dynamic VE, first pull, 463.
I attached in case you don't believe me. I personally do not use Blue Cat or do any sort of VE Coefficient tuning. It's too easy to dial in a MAF curve and call it a day.
ON BOOST THOUGH I want a VE table. Fortunately as everyone is agreeing, the MAF's on these cars are great and so far working flawlessly on high HP boosted apps.

Again, I'm not looking to argue with you or anyone else, but you are incorrect sir.

It's my understanding that one had too much timing, and one did not have a clamp installed on the inlet tube. The owners can clarify if I'm incorrect.
It's not surprising they are both ECS kits, simply because we have the most kits on the streets at the moment.

bluecat works but the HPT custom OS makes it CAKE!!
IMO, it really depends on the rest of the combo. a supercharger doesn't really introduce issues below 3K RPM or so with idle and driveability, which is where speed density really shines. even GM doesn't use VE over 4K RPMs in stock calibrations, MAF is fine. when you have a big cam with lots of overlap/reversion, relocated MAF sensor, etc then using VE until the airflow smooths out can really help driveability. an otherwise stock engine with a supercharger, nothing wrong with MAF.

The 2bar reads up to 14.7 PSI. It will give the best resolution for the meth kit. Has nothing to do with tuning or the vehicles PCM.
Think of it like a 15 lb boost gauge
Simply hook up a boost source to it or T into a mechanical gauge.
On centri blowers its the best sensor to use as a general rule of thumb.. boost climbs.. meth hits harder.
