Hey guys,

Long time lurker here.

I've been reading up quite a bit in the past few weeks doing my own dd in-regards to making more power, but still would like to ask for advice before pulling the final trigger since people here seems extremely knowledgeable (at least way more than me).

I have a 2019 3.0 and I currently have the following mods: a catless DP, intake, chargepipe (titanium, got it because it looked pretty), and an exhaust (scavenged off FB, too good to pass), AP 5000r running with re71rz tyres at 295 square, with no tune just yet (waited for warranty to expire).

It used to be my daily, nowadays it's really just my weekend car that I cruise and occasionally touge/hill climb in.

As per my next steps, I am thinking of adding a flex fuel kit to do e40 and then a custom tune, to my understanding, with stock turbo and nothing else, I should realistically be able to achieve 500hp?

Frankly, I've never driven a car at these power levels, the most aggressive car I've ever own/driven was probably a frankenstein K20/K24 EK back during my more youthful days...

Could I get a reality check, and perhaps someone could tell me jumping from stock power to 500HP is a bit too much? Should I ditch the idea of flex fuel kit and just get a tune?

My only concern with just getting a tune is that my friends been telling me "might aswell go all out in one go and tune it so you don't waste money re-tuning if you decide to add more mods down the road".

Appreciate any advice/wisdom

E40 OTS maps from MHD or BM3 should get you somewhere in the 470-500 WHP range. Custom tune can get you a tad over 500 if it's an aggressive map, but I don't think a custom tune is worth it on stock turbo unless the OTS maps aren't smooth / run poorly.

As for mods, there really is nothing besides downpipe that adds any meaningful amount of power before a turbo upgrade.

If you want to guarantee 500+ WHP or make more than that a turbo upgrade is the only way (unless you wanna deal with meth injection, which I don't understand why anyone would do that over one of the smaller upgraded turbos...), you can get something small like a Pure600/650 for not a lot of money and do 525-550 WHP on E40 no problem, but you will have to buy a custom tune to make the most of it / ensure reliability.

Personally I'd just go MHD and buy the OTS maps pack and run the E40 stage 2 map until you're bored of the power, then look at a turbo upgrade and custom tune.

Supra doesn't need a lot of mods to make big power. You have already the important ones.
Maybe an intakte manifold depending on temps and what you do with the car, but that does not need a retune.

IMO it's also the best way not to go fully crazy with the power if you have never driven a high HP car.
