Marcin,
I read this on another forum and I was wondering what your opinion was on this.
Car in question was a Procharged corvette that made around 930 rwhp. The tuner we asked why he used a MAF tune instead. This was his response
By cutting the MAF table in half and using a LS3 Sensor in a 4" Tube you QUADRUPLE the MAF limit. With the HP Tuner extended Hz Range hack you cannot peg the maf until 15000 + Hz. Which means you can control the entire fueling of the car with the MAF table. Very similar to FORD Tuning.

He's right. You scale the IFR/MAF accordingly. Same thing you have to do with FI ETC cars, even with a 2 bar SD OS. Reason is, they still will set a 1514, even if you max the 1514 table. Especially the PD blowers, that make a bunch of boost at the hit. I've had to scale some of them by 50%. You end up with numbers that don't make sense to anyone except people that have tuned those types of combos.
BTW, I don't like tuning anything FI with a MAF. SD all the way.
I _HATE_ scaling tables. It's justifiable (barely) only in the most ridiculous of situations.
I hate to hijack threads, should we start a separate one?

Sometimes you have to. I guess you don't tune many LT cars? Or older chip cars, like SD LT1s or Buick GNs?
We should spin this off into another one. Wanna take it to the tuning section?
