Has anyone had any experience with either of these tune units. On surface seem to be similar in improved performance on Golf 169kw but racechipone is only $200 Aus vs $600Aus for the Jb 1
Their numbers seem dodgy to me. This video which is actually by Racechip shows their 'ultimate' version ($749 worth) only adds 41ps over the stock 319ps. $749 for 13%? Yet their website says 30% more?
Seems someone at Racechip needs to correct their website, this is false and misleading.
I bought one and installed it but it proved to be faulty. I'm waiting on a replacement one but am going on leave so won't be able to install it until I get back in August. Will post the results here when it's installed and (hopefully) working.
The JB1 is well proven both o'seas and here in Aust to work quite well with noticeable power gains (see the vwgolf.net.au forum as many on there are using the JB1).
A very well respected tuner from Sydney (Mark from Recode/Revlimit who has tuned some of the most heavily modified and fastest Mk6 Golf R's and S3's in Aust) has been doing extensive testing with the JB1 on his own S3 on the dyno and the results even impressed him. Its not as good as a proper tune, but for a tuning box its very good.
For that reason alone i wouldn't even bother looking at the Racechip.
For the record I have seen a 8hp dyno gain on the above mentioned fuel only One chip, right before the owner put it in the bin. As it just ramps up the rail pressure, without any extra boost, you just make the whole rev range richer. Talk about fuel use vs minimal gain.
The JB1 is multichannel, so they are chalk and cheese.
Misleading is the word, we struggle to see those sort of published gains at the wheels on a proper 3-4 channel piggyback with a custom tweaked tune.

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.

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
