Now i have astra coupe turbo which ever since i had it remapped it has been hestating at around 2-3k revs mainly in second gear. Oggy at reddot did meantion that it seems to pink but he mapped it to try and solve it... it never went though... anyway the other day i found a bottle of STS boost power stuff (orange coloured bottle which i had brought from halfords) So i thought its been sittting here for like 3 months let me just put it in the tank. Tank was approximatly 3/4 full. well i drove it the following day and ever since i have not had it hesitate once. that was 3 days ago now..
Now i use BP petrol anyway the normal stuff and its hesitated whether i used ultimate or normal so why pay extra if i don't get any benefit...
I did read on the bottle it stops pinking/poor running etc etc etc.
Guys give it a go and let me know if you have such joy as i have found or if you have cured hesitation in anoher way as i am assuming that once the petrol runs out and i fill up again it will return as that stuff is no longer in the tank??
Thanks for reading... good luck..
