Quite induction

Boost 6-5-9 is the default setting for running super unleaded/V-Power fuel so explains why the boost figure is lower than it could be. Boost request isn't static, it will vary depending on current conditions, Load, RPM, throttle request etc.

Pretty sure Revo don't map around it as such and just try to boost through the surge point, so said hesitation/flat spot sub 3700rpm (ish) will be no better, worse if anything.
Just what I've read over the years, hope I'm proven wrong :happy2:

When I originally had Revo Stage 1 installed, they recommended 6B / 6T / 9F for vpower but could use 7B also for a more responsive drive. Obviously I did just that and it ran very nicely. When I recently had the VIS hpfp fitted, Revo said I could richen the fuelling to 6 or 7 and run boost of 8. This time the car felt rougher on the more aggressive settings and I went back to 7 boost and 7 fuel, where it runs more happily. This is in the context of a K03 car however I think you can likely up your boost and timing settings a notch.
Dan_FR:
No guessing, Data logging needed. Timing 6 is quite a strong request for V Power using F9 (the leanest request possible) and would need logging to ensure its ok. Revo only suggest F9 to try to work around the lack of fuel available at low RPM thanks to the standard pump and keep the car operating within the 25% correction window that the ECU is capable of.
Felt rougher how, and under what conditions? day to day driving?
colesey:
Data logging is always a good idea and fwiw my car was originally logged satisfactorily during summer on the settings (T6 / F9) you feel to be aggressive. That said, not everyone has easy access to open unpoliced roads or dynos to facilitate logging and therefore place some reliance on manufacturer’s recommendations.
Anyhow, more recently after the new stage 1 VIS hpfp was fitted with Revo’s more ambitious settings, the car felt rougher running in day to day driving, being lumpy and unhappy on part throttle.

I didn't say aggressive, what I meant was everything needs to be pukka and happy in order for it to be ok on that request. Not all cars are though which is why I would always recommend logging unless you go with a much lower/safer request
I'm not saying i don't believe you, but find it odd that it was the day to day driving that was affected since the settings change the WOT requests. Day to day driving the ECU runs a stoich mixture and huge timing request. I've never noticed a difference with mine running lower settings in terms of drivability, only at WOT.
Mine runs B9-T7-F6 I think? But then again I use WMI so not comparable. Still, as long as people are happy, thats all that matters
