hey i just got this turbo 1.6 in a trade and don’t know a whole lot about it but on hard pulls it does this breakup in boost, trying to figure it out but not sure what’s causing it, it is untuned and doesn’t run great in the first place but not sure if that would cause it

 

is it untuned on megasquirt? Is it a stock ecu? Got something like a voodoo box? Its stupid to be going into boost on an untuned car.

If your on standalone may have a boost cut.
Your plugs might not beadle to spark under those boost levels with stock coils. Run NGK BKR7E and gap them to 0.020 - 0.03"

This issue could be saving your ***. Go tune your car.

 

Failure takes many forms.

 

Thanks for the advice, I will keep it in my mind.
