Thinking through all the mods I want on my fg and I'm trying to work out if it's worth doing a bit myself before getting it tuned or if its not really worth it. Basically I figure I could handle installing something like a pw stepped intercooler and piping kit and a battery relocation kit with turbo side intake. I know it will be pretty satisfying so there's that aspect too, but what would that stuff cost to be installed anyway? Eg pw stepped cooler kit is like $1595 direct, but what would it end up being installed, would the tuner get it cheaper anyway and hence labour not add up much past retail? I'm also wondering if tuners wouldn't really like it if say I walked in and said I have these power goals and I've done these bits myself, whether they'd not guarantee things as much, or if they usually go a bit easier on price when you get a big bulk of work done together and any savings from the diy would disappear anyway? I know I see on here all the time ppl talking about their diy projects and then all the places like rapid and other places selling kits, so I wanted to go that path myself, but if it isn't really worth it when taking everything else into consideration then I wouldn't bother. Cheers.
