LSA missing/hesitation

[Eldest23]

Hi guys
Seem to get a slight miss or hesitation while under load in the car and when going from one gear to the next it seems to hesitate when the throttle is re-applied.
Any help greatly appreciated

They all seem to have it.

Is yours modded? Might be worth checking HT leads.

My LSA doesn't do this. Perfectly smooth and linear.

haven't noticed mines doing anything like that either,,,,
Like said I'd make sure all the servicable items are 100%,,,
Check for boost leaks,,,
wouldn't rule out Crappy petrol either

Stock factory tune seems to have a fair bit of knock which can cause quite a bit of knock retard on low quality fuels. Knocks just past 2500rpm and again at about 4000rpm.

yeah it is modified and all the stuff is brand new have looked at the leads and plugs but can't see anything obvious.

Both of the cars I have access to have the same hesitation / missing / knock.

Standard cars.

Standard cars.

What fuel you use Bart?

[BartW]

Admittedly standard unleaded. You think I should go a higher octane?

[HappyMidget]

Yup, stock timing is really quite aggressive the the higher octane really helps.

I use the high octane fuel but still have the same issue.
