Racechipone vs JB 1 plug and plays

[Micloi]

I'm running a JB1, along with downpipe, intercooler etc on my R. I have to say, I'm super impressed. The JB1 is about 70-90% the power gain of a tune, for substantially less cost, and keeps your warranty intact.

Did you dyno it before and/or after please?

Here you go, all totally stock hardware. This is on our dyno which is fairly cruel

Stock S3 Vs JB1 V's our stock hardware custom tune (12.1@112~114 ish tune that is)

The JB4 is miles ahead of the other option mentioned just don't.



Power, compared to stock you can see with the JB its a really good gain everywhere - its just works. You can also see the AFR's here too sitting at 12.4~12.5 which is fine (and you can also see mine which is a touch too rich for peak power but fixed now )

You can push these interceptors harder too but beyond this point the AFRs skyrocket into the 13's so its a bit risky and yet I've seen a few cars that run like that all day but for how long ?. Same goes for the ABT unit too.
The JB device will eventually have a lambda option to add additional fuel.
Oh blatant plug for me the - tune is another jump up again especially down low

I don't sell the JB FWIW there is simply no margin in it for me but yep it works

Thank you parso_rex

Was actually very interested in @Primordial 's dyno with the intercooler and downpipe.
