Gday all

Can I put a standard acuator back on after having an 11.8 one on there.the tune is 8 psi which is to small for the bigger acuator but would be fine for the smaller one..can I just swap them over or will it need another dyno tune

How do you run an 8 pound tune with a 12 pound actuator? What's going on with tuners these days? Or did you change the actuator yourself without a retune?

No bta put the 11.8 acuator on it and dynoed it only at a 8 psi tune because apparently my valve springs were stuffed and if I replace them the tune will be fine..but I replaced the springs and it still surges under hard acceleration..I put a standard tune in and it runs fine untill 5000 where it hits boost cut but no surging at all..so im thinking if I put a standard one back in it should be fine with a 8 psi tune or am I wrong..

Well id be careful with both tunes then...it can cost you alot more than 2k if you blow the engine up
