Daily driver, reliable power upgrades, help?

[d2jlking]

Hello all. I am wondering what recommendations you would give someone who wants to increase power, while using their new Supra as a daily driver. I don't have a hp number goal, I just want to have more power (or assume that is what I want). I haven't even taken delivery yet. Anyway, I will be commuting in this Supra, taking the wife for drives on the weekend. I just want the care to feel powerful and still be able to rely on it.

Catted downpipe, ecutek/mhd/bm3, should get ~420whp. Add flexfuel with e50 and youll get close to 500. Your ECU will require it to be cloned in Russia however, but having an unlocked ECU is worth the cost over using a JB4.

I recommend you drive your car and enjoy it first and learn your car while stock. People on here are so fast in just throwing parts at it. The car is more than capable out of the box.

The ecu comment is only if you buy a new one or late production 2021 and forward.
mad suggested though, downpipe, tune, intake and charge piping

This ^.

If you really get jonesing for more power after you've gotten used to it, catted downpipe + JB+ (or JB4). JB4 + Meth is good for around 500whp.

I had mine for 3 weeks and not even 500 miles before it went straight to Visconti for tuning and flex fuel. Many people including myself have zero desire to drive a stock car that is just like every other car off the dealership floor.

Personally wouldnt even consider a JB4 as an option. Our engines are worth more then $600 bucks and tricking the ECU into doing things it doesnt want to do is not how you make it reliable. If you cant afford the current flash process for the newer ECUs wait for something else to change/save for it or leave it stock.

it seems like you're implying that the jb4 is not as reliable as a standalone tune, is there any evidence or data confirming or denying this ?

I think they're referring to this thread.

Kids like this are exactly the reason the salvage thread is 70 pages long. lol.

JB4 is more than capable. The only folks that should stay away from a JB4 don't understand what it's doing or how to read logs. Modern engines are not some mystery box doing gods work or whatever.

JB4 is absolutely safe - it's just a tool, and saying anything else is FUD.

But then again, what do I know. ¯\_(ツ)_/¯

Wagon before the horse..

Enjoy the car stock until you’re bored. Don’t feel pressured to mod right away, stock power is still pretty good.

People are wrecking cars because they are turning off TC on the street. I've been racing for 10 years, not interested in stock. I've also been tuning motorcycles for just as long, where piggy backs like power commanders are popular.

Piggy backing modern ECUs is the cheap way and its tricking the ECU into doing something it doesnt think its doing. They are closed loop systems where all parameters effect others. Its a needless risk for no gain and just because you can doesnt mean you should. No tuner is going to recommend a piggy back over a dedicated solution. Cheap, Fast, Quality. You only ever get to pick two.

Somtimes it has nothing to do with price, it has to do with availability. I’m sure you’re much more experienced than I am, with 10 years under your belt, but based on what I’ve seen over the little time I’ve been doing this, sometimes you do what you have to to make things work. There is nothing ‘unreliable’ about controlling the WG and manipulating the pressure the system is seeing. As long as you understand what you’re doing it’s fine.

Hell, it wasn’t that long ago when a RRFPR was _the_ way to manipulate fuel pressure on boosted cars- especially those that didn’t come from the factory with a turbo.

Ya just make due. Locked Bosch ECUs are a real hurdle, believe it or not. There are a few folks that did the whole dance to Russia, it’s not a majority of owners, it’s a very small fraction.

It’s hard, there are hiccups, it takes a while, gen2 B58 ECUs are hard to come by these days, etc.

Welcome to the community. JB4 + catted downpipe is a good plan, like zrk said. It's certainly a good starting point. A set of stickier tires might not hurt. That said, the car is damn quick in showroom stock trim.

Thats like hardware engineering 101. If it doesn’t do what you want you redesign it, you don’t push it out of its limits by tricking it. How many JB4s were shipped that just straight didn’t work out of the box? Users went through multiple units before one worked and the response was “oh some times it’s a bad unit”. So if you are willing to plug in a device that has not been properly tested into you 20k engine go for it. That kind of hardware will never touch my engines.

Sometimes patiences is worth it. Yeah the Russian dance isn’t great but that’s why I instantly got it tuned. I’m not willing to run a piggy back so sent it out. It’s not my daily so it’s not a problem. Personally I would just wait and have a stock car until a proper flashing solution came about then running a piggy back.
