Default getting a custom tune couple of questions.

I need to get a tune asap, my ses light is on and my inspection sticker is a year out of date lol.
All my current mods are in my sig. My question is if I continue with simple bolt-ons such as UD pulleys, 160* thermostat, I shouldnt be needing a retune because neither cause any changes in air/fuel correct?

I do plan on doing a fast 92 set up which I know would be best with a retune but thats later down the line. Im working on getting the most out of a bolt-on car until I can do h/c/i.

You need a tune after slapping the headers on. With your mods untuned, you are leaving about 15-20 whp on the table, gas mileage is suffering, etc.

I know that which is why I am scheduling a tune shortly. Im just asking if any other boltons other than intake maifolds/fuels systems need a retune?

I apologize, no you should be fine with the other minor things. I would strongly advise against a 160* thermostat however. The tune will take care of keeping it cooler with the earlier activation of the fans. If you get it too cold, you will start getting condensation. Engine needs to operate around 210.

To be clear, a tune isn't really required after headers...but it is highly recommended. I installed headers and ory in December and it hasn't been tuned yet. I know I haven't gotten the performance gains I would have tuning it right away and it is running a little rich. If you're not doing any other major mods within the next 6 months or so I'd definitely tune it.
