They dont remove speed limiter, only remove boost cut.
To remove Speedlimiter, Cut wire 53 on the ECU.
What i am going to do is wire in a switch so that if i wanna go fast, i just flick the switch and 200+ is there for me.
Althou Zdenko, there is no way u are goin to his speedlimiter down the 1/4 unless ur car is very modified.
