I have all those parts or similar new under $300.
Anyhow, at least with tuners you pay for knowledge, expertise etc. Saying that there seems to be a lot of my way, my parts or no. Stage one. stage 2, stage 3. That will be best for most, but if someone comes in and has done their mods correctly or researched what they want, prices vary wildly.
Sorry I'm gonna kick here, not happy about what real dyno is doing.
