Does anyone run the Dellorto Update Kit ?

I have Dellorto 40's and use to run 34 vents and 140 or 145 mains

I put the spray bar update kit in a while ago and you up the mains to 150's

It ran/runs fine.
No massive power increase.
On decelleration there is a bit of a burble.

Anyway - today I put the 140's back in because........... well I had nothing to do and the car was running fine, so I thought I would just put them in.

Anyway - the car seems to run better. Crisper. The deacceleration burble seems to have gone.

I am not appearing to get hot - just running one of the dip stick sensor things and feel

I am now putting the 145's in - bit of safety.
Just nervous changing from what CB recommend.

Just interested if anyone else is running and changed from CB's recommendation

Not sure about recommendations, however I'd always trust a wideband as every motor is different.
Do you have access to a wideband to check it?
