On a road car....No...its just for fun, if you compete and have something substantial then its useful I guessI thought anti-lag was only required on cars with large turbos (Rally spec cars with large turbos)
The ST turbo is dinky so doesn't really need anti lag.
I stand to be corrected though
I had a 1993 wrx-ra running 350bhp, it was mad off the mark. This had an ecu with anti-lag capable, it just needed dialing in...to be honest its a real turbo & engine life shortener so decided that 0-60mph with the set up I had was quick enough, plus a smaller turbo spools much quicker than the big blowers tend towas just wondering as my mate has it on his subarau running bhp and it sounds amazing
