Just installed larger injectors into my AGU. Everything was running nice and smooth for a good few hundred miles/ few days until last night a severe flat spot problem occured.
Its still holding/creating boost fine during the flat spot but it has barely no power until it kind of splutters and jerks back into life again towards the top of the rev range.
Im really confused to what this might be?
Also, are the 360cc red top injectors a straight swap?
