GooseTuned via HPTuners on a 2021 PIU - Basic mods make EPIC power on the dyno on 93oct!!

[GooseTuned]

As you guys know we set the bar for PIU tuning last year when we were the first ever to 11s 100% stock, full weight, 0mods and on 93oct.

After that we immediately took the stock turbo explorer world record, running 10s over 40 times, and finally taking the official track record as the first ever PIU in the 10s!!

Now, we're back with another very very cool car!

Ben reached out for tuning a while back. We finally got him on the dyno with a simple mod list:

Mods
Fenfab v2 intake
CVF intercooler
Catted downpipes

Fuel
93oct e10, so no added ethanol for instagram numbers

The results are unreal!

493whp 528wtq *on 93e10*!!!! You can see up top that we have reached the knock limit. But the power is incredible. On a cooler day this car will make 500+whp on 93oct!

I'd imagine this setup will make close to 580-585whp on E40. This car just flows!

Let me know if you guys have any questions!

How many miles on that PIU?

I know you've been tuning the hell out of PIUs, is there some sort of significant difference between them and an ST that makes them seem to respond better?

Good question! Let me ask.
Most are very high miles

Better suspension, better gearing (subjective), bettwe transmission (objective).

Keep in mind it's also heavier.

It's hard to believe that none of this stuff was really ever documented over its six years of existence before we touched it. We learned a crap ton all of 2025. But the results showed as well.

Good to be able to continue to push the platform forward and give others new ideas all at the same time!
