wat does e30 mean

30% ethanol blend.

Although you don't know what it's blended with so it's somewhat meaningless because that can change country to country.

The fuel specified for your car at a minimum.

Its fine to run 87 on map 1.

Map 1 87 octane

Can you guess at the numbers from using Map 1 with 87 octane? I'm thinking about the purchase but I don't want to upgrade my clutch. My goal was to use a very light increase.

What car do you have the JB4 fitted too?

2022 us spec gti

[George @ BMS]

2022 us spec gti

35hp minimum.

If you got the means to log it get some logs through to me in map 1 [email protected] and I can check if there is room for improvement.

I haven't purchased one yet. I'm considering clutch wear, i think if i can keep it under 290tq maybe the Stock clutch will be fine

We can adjust the torque with a custom map to the point you happy.
On the ready maps up to map 3 which requires 93 there have been no premature clutch wear reports.
