I have said it since the start. The 2021 uses the same turbo and the same fuel pump. The 2021 has lower compession which lowers efficency on ethanol. The 2021 on a stock turbo with ethanol may in fact make less power. I have tuned a few and haven't noticed anything special on the 2021. If...

Remember... not all dynos read the same. Just because you made 447HP does not mean that it would make 447 on a dyno that made 500. The stock turbo maxes out on pump gas. The ethanol allows for more aggressive timing which is worth 50-100HP. As well as the ethanol tunes dont get as much shift...

Yes i do map switcing on ecutek all the time. There is even flex fuel so if you have to blend up or down the car will auto adjust the tune even.

The stock turbo will start heat soaking quite a bit after 100MPH. You can do pretty decent with a quality drag map on E50 + DP. I can get people to run 10's with just a downpipe, ethanol, and tires. However if you are roll racing you will make more power at every rpm with the pure 800. But the...

Yeah thats not normal... I would have to see a log to see if any states were flagging. But it might actually be a damaged ECU/DME. Or a bad programmed ECU.

There is an issue that may be a bug in the factory calibration where sometimes the car will rev and hang. And then it doesnt like to rev for a period of time unless you restart the car. I cannot see the video due to forum being in limited functionality today. I would also need to honestly log...

A very slight difference. I made a post under this or the main MarinTuned account showing HKS drop in on a car pushing 95-100% WGDC showing a slight airflow increase. The lower pressure drop helps a bit. An aftermarket intake can increase filtration media size which gives better filtration than...

Also its just an intake tube... There isnt even a MAF sensor in this car. There is a simple pressure sensor in the intake tract. The only time i have seen a check engine on this platform is on the first gen B58 there are some intakes that the connection to the PCV system doesnt seal and causes...

Ill say it one more time... I highly doubt you will get ANY power on a factory tune on this intake. I have yet to see any intake make a car faster than the other and a number of records are set on stock airboxes. These are mostly for noise. These cars use a torque based ecu and the car knows how...

Its confusing. And the marketing teams dont always work with tuners and arent in the know of all terminology. It happens all of the time. It didn't help that toyota at one point referenced 2021 as A91's...

It likely has little to do with Toyota and more to do with Bosch trying to protect their intellectual property and fixing a security flaw that has existed for a year. Bosch is fairly active in trying to secure their computer technology.

No

Personally I dont like pushing them past 550-600HP on meth. Once ou push further than that the front cylinders run too lean and ive personally killed plugs before. Meth is not a substitute for port injection. You really need fueling for each individual cylinder. Mind you I have pushed deep into...

I will be in both socal and the bay area in a few weeks. =)

Intakes are just for sound. You get a small bit if you are leaning on the turbo hard due to the reduced pressure drop accross the filter. This also gives a very small but not noticeble transient response improvement. But the power on the car is regultad by a torque controlled system and it will...

Is your car one of the special edition cars? I have unlocked many 2021 ecu with that exact calibration in it. The A91 special edition car has a new bosch mg1au ecu instead of hte bosch mg1cs ecu in the 2020/2021.

I have had zero turbo failures on the cars I have tuned. But I have seen some randomly fail that were tuned by friends of mine. There may be a mild quality control issue going on. I have plenty of people running stock turbo on flex fuel maps. I did it my self for 10k miles and I tapped over...

I'll be at a casual general car meet tonight if you want to come say hi tonight. ✌

CSG in California sometimes does them. I was considering getting a few of their catted downpipes to keep in stock. Reach out to CSG (Counter Space Garage) and tell them I recommended a red start and see if they can get you one.

Mt Lemmon, and we also need a northern AZ one! Once I figure out the schedule for my next cali trip over the next few days I was goin to post up asking for interest. Me and my girl will make the treck down for a Lemmon run.
