hey guys, having a bit of an issue that I could use some insight on, stressing me out hardcore. ive had a bit of a read around the forum and ive found a few answers. I have a ba xr6t auto with, plazmaman cold side piping, under battery intake and process west intercooler, 4' dump, 3.5' cat, twin 2.5' pipes, 60lb injectors and have had it tuned in syd. I have nizpro valve spring that il be installing real soon. it made 320kw @15psi and while it valve bounces a bit atm (only under WOT), under moderate to heavy loads ive noticed it spikes boost. gauge goes upto 20psi so its probably spiking higher than that. I figured the culprit would be the wastegate actuator and after reading around abit have found they are quite flimsy and I should upgrade this. what actuators is everyone using and whats working? im leaning towards buying a 12psi actuator. (anyone bought turbo smart?) will I need a retune after this is installed? (I really hope not) do I NEED to do the flapper mod as well or is it reccommended? I will contact my tuner when I get some parts and cash together but just seeing if anyone can offer any advise as I have too many cars and not enough money and this is a real bummer as I havent been able to feel any power this car has practically since ive owned it. plus I dont want it to throw a leg out of course.
