Getting my car tuned next week and was wondering if a 12psi actuator can be installed before I take it in. I know this means the waste gate wont open but if I really baby it will it be ok or am I asking for trouble.

I would, but I like risks and complain when they don't turn in my favor.

Seriously though, Im driving to my tuners with every mod installed except for surge tank and injectors... that includes a gtx with 12psi actuator and ported wastegate.. and a 4 inch turboback exhaust.. let's just say a few horns will be heard at the pace I plan on driving..

Yes you can do it. Drive off boost and you wont have an issue.. Buuuuut if its an adjustable actuator I would suggest waiting and getting your tuner to install so he/she can set it to their preferred preload

Its just a fixed actuator but I'm thinking if my valve springs are too soft and won't take 12 psi or more then the actuator will have to be removed again and replaced with a softer one

Just had to rebuild my motor (thought I had a piston ring problem when I bought it 2nd hand. Mechanic said he did compression test but turns out he didnt do a wet test.) And combining that and bolting on all my mods like yours, I ended up loosing compression in a cyclinder and I stayed off boost. Cost me $10k but built by Atomic Performance and good for 698kw now.

Ps. Changed mechanic aswell.

Dont do it. I wish somebody told me not to. Unless u got cash to do the above.

Good luck with it all m8. Even though I had a costly experience, im glad I got the Atomic rebuild. Its cheaper to do if u havent busted your motor too.
