Hi all,

Ok just to recap i have a Jabba Remap this was set up to run on 95 Ron, and does very well since i had it... for the first time last week i put in Optimax to see what happened...well at the moment my car hates it... lost about 5 psi in boost pressure... and once it wouldn't boost past 5psi...im assuming this is due to me putting a higer ron petrol in when the car is set up to run on 95... BUT!!! this isnt the first time this has happened its has happened in the past i filled up with 95 from a jet garage and had similar problems thinking it was 'bad petrol' i filled up at my normal place and every thing was ok... does my car get the hump if i fill up at a diffrent petrol station does it have AI!? lol

or could a sticky throttle body be to blame how would i go about cleaning it??

Mike remapped my car for 97 RON and it doesnt mind 99 RON, so I doubt it is the fuel causing it.

No idea what it could be tho, sorry.
