HPF POWER UPGRADE | Toyota GR Yaris Stage 2

We are super excited to announce our GR Yaris upgrades! This was the first Yaris we got to play with and it already had some mods done to it which were equivalent to our Stage 2 pack so we were keen to see the results and they did not dissapoint!
HP-F Stage 2 Yaris GR Package Includes -
1 x Before dyno run
1 x Custom ECU dyno tune
1 x MST Cold Air Intake
1 x GRP catback exhaust system
1 x Process West Intercooler Kit
1 x Labour to fit, tune and test
As an introductory offer, we will be doing the Stage 2 upgrade for bookings made in March/April 2023 for $7,000. That's $400 off the normal price! Even if you just want to do an intercooler and tune we have an option for you. In conjunction with Process West, for bookings made in March we are offering a tune and intercooler including all labour for $2,895. Again, that's a saving of $400!

Curious, as most overseas tuning firms replace the turbo downpipe in the first of mods. I can't really see the cost benefit/power increase from cat back exhausts, when the flow is already restricted by the time it reaches that point.

[@parker4316]

The biggest exhaust restriction at least here in the UK comes from the GPF not the Cat. Most of the “stage” 1/2 packages I’ve seen aim to remove this. I think it’s quoted to be around 20hp gain from removing it. And I don’t recall seeing any tuned car pushing over like 300hp with it present.

[@christmasisawesome9348]

​@parker4316 remove GPF plus higher flow rate downpipe, and a custom tune should get you to low 300

[@parker4316]

@@christmasisawesome9348 yeah I have similar on my GRY. Currently running a full decat and GPF delete. With a tune getting 327hp.

[@remyche8768]

I want 300hp at the wheels, i have a rallye stock, and love it. Goes hard for what it is. Such a fun responsable daylie driver 😅 not what im used too.

[@Nishan113]

173kw max? Surely that’s not right, even with the all-wheel drive loss accounted for. My stock gr yaris with Akrapovič pulls the same as a Megane 300 trophy.

[@remyche8768]

Think so with stock valve springs. It's like 22psi stock, more boost will cause valve float. Put in stiffer valve springs and can up the boost

[@Silverwarhawk]

Butt dyno doesn't mean shit lol

[@WithSeb]

can you tune the stock ECU or does than need the full upgrade. Looking to get the antilag / pops happening

[@artistintheambulance]

No you can tune the stock ecu however the results are still hit and miss … can’t do anti lag, pops and bangs is just over fueling on decel not anti lag 😂

[@christopherbassit2757]

Got my gr corolla 2 weeks ago

[@gtrlife2941]

Hi do you remap the factory computer

[@Houlque]

173 kw is approx 275 PS. Stock car claims to be 265. Threre should be sthng wrong?

[@aceytoja]

Could be power to the wheels vs crank.

[@robertsaca3512]

Needs motec etc. for serious power. 173kw isn't enough, even a model 3 rwd will leave it behind.

[@tonyw2960]

agreed for serous power you need an aftermarket ecu but comparing it to a model 3? seriously 😂 when you come to a b road like it was designed the yaris would make short work 😂 it's just a bonus it's a great track car too

[@cilviademo]

That wasn’t 300hp but? Lolll

[@fusemalaysia840]

yeah dude, Yaris is 3 piston, mean you need 2 ECU for each row

[@NorthRage14]

We want GR YaRiS 3.0 diesel turbo!

[@artistintheambulance]

Hahahaha - what a joke lol
