n249 difference

[dippy4000]

Has anybody done a log with vag-com or on rr with the n249 on and off?

I tried today using the liquid as a reference, i know its not 100% accurate on some points but good as a point of reference as i said. i did it as the torque graph was showing some irratic blips at 3700-5000rpm.

after the run with it not on i put the n249 back on waited an hour and went for another run(both runs done in 3rd).

with it on the peak boost was 0.8psi higher, the bhp was up 7, torque up 9 and the torque and bhp curves were much, much improved, so ive decided now to keep it on.

What findings does any others have as said with vag or rr?

Cheers all

Yep, i did, only logged boost curve though and it seemed like a smoother curve, also bare in mind the sensor stops reading at roughly 22psi, my boost peaks are over this.

So we're saying its better connected for peak power even tho it drives better disconnected?

I found it better bypassed, for boost anyway, see my post in previous message

Sorry I didn't see the link I read it as better bypassed

thats what im asking on other peoples results.

i see on the above on boost figures it smoothed yours out, whereas on mine it gives better peak power and smoother curves with less flutuaions with it on.

im not saying its better, it just seems better for my car, though mine in not a LCR, i dont know if this makes a difference or not

its been a over a year since i had mine on.-. forgot what it drove like standard

Mine was allready bypassed so ive no idea what its like with it on, but if its worse than this then cant be good.
