You're confusing MAF with MAP. If you change the housing size for a MAF, it needs to be recalibrated. No ifs ands or buts. It has been proven many times aftermarket intakes show minimal to zero gain over a stock 2018+ airbox on a dyno, and thats intakes with larger diameter maf housings.
You just sstated exactly what I said. The maf will compensate for many aftermarket intakes, hence no tune required. I agree that the gains appear to be minimal, but that's not what you said. You said "Everything that you do to these cars that effects airflow requires a tune." Which is still not true.

Without a tune, you're not making any large amounts of HP.

Remove the cats from these cars without a tune, and you'll still have Cat overtemp protection dumping fuel when theres no need for it, which is a power loss. Relo the front O2's to a collector without a tune and you'll have transport delay issues.

I wwa only arguing your first two points in the post I had quoted.

but you knew this right? You've looked at the calibration table layout of a S550 right?

The thing is, you're not going to be able to show me anything that proves your point.
There are many dynos that sshowgains with exhausts or intakes, yes they may be minimal and that is for the purchaser to decide whether the gain is worth the price. There is even a dyno sheet regarding x-pipe vs h-pipe on the same exhaust showing hp/tq differences

Wow, the best I could do was a 2.03 60'. I only had 25psi in the rear 285 Michelins, 1/4 tank of 91 because that's all we have, fronts pumped up to 45psi, air filter out so the box was empty, TC was off, skipped the water box, had the OE active mufflers were open, power braked it to around 2k, then had the emergency brake on until I felt the tires digging in, I think I gained about 300rpm. I tried it in all modes and the fastest was standard and letting the trans shift itself. I'll be interested in seeing what the FPP CAI/tune will produce.
I'd say the 1.7 60's was incredible with the stock converter as my 70 Maverick only cuts a 1.29 60', although runs 9.80's @ 136.

Oh man love Mavericks!!

Everything you do to these cars that affects the airflow is going to require a tune.

A tuneless cold air intake uses the stock size MAF housing, it will not add 1hp. A catback, will not add 1hp.

A cat delete x pipe/h pipe is going to require a tune. Headers will require a tune.

Roth its the BAP/Speed Density cars that normally need a tune. The MAF cars can adjust to a point. There is a wire in the MAF sensor that has a heating element. Thats how it measures airflow by the amount of voltage required to keep the wire to a certain temp. Once you go beyond the voltage that can be supplied the MAF Sensor would now be out of spec.

Once again, MotorIQ in the article I posted saw almost 13rwhp in a full catback Borla S type exhaust with a dyno done at Palm Beach Dyno. The baseline was inline what a stock 2018-2020 gen3 cars make. A lot of times they show a low baseline and then do the parts only to get back to to the point a stock car should be making and claim it made hp when in fact it didn't. There is a lot of credibility in the test done. The link again..

the MAF is not going to accommodate for a larger MAF housing. It requires new transfer data.

If you stick an aftermarket intake on with the same size MAF housing, which is what no tune required intakes are, its not adjusting anything, the car thinks it has a stock intake on it, since essentially that's what it is. No gains to be had.

I knew this graph was going to get posted.

1. The runs are well within a run to run Dyno variance. Why not a few stock runs, and a few modded runs?
2. I spoke to a few people who did that test on that same car, you do realize, they basically drove to PBD, immediately strapped it to the Dyno and ran the first test (stock). The second test was done after a few hours and a cool down.

Dyno discrepenacies on normally aspirated cars are generally a few hp not 13.
