I’m not a tuner, never have been, never will be… So I’m a little annoyed about the three achievements for getting credits from usage of tunes. Specially with the 50/100+ requirement before credits are awarded.
So I’m here, asking for help. I’ve used the thread on here about tuning for beginners (upmost thanks to the OP on that) to fiddle with a Formula Ford Ecoboost 200 in the hope I can get people to use it… This is what I’ve done…

Dunno as it won’t let me change anything
What can I change to make this useable and hopefully downloadable so that I can get enough people out there using this tune?
I’ve tuned some other vehicles, but they’re so poorly done that I don’t think it’s worth mentioning…
If you’re a new tuner, there is a great post on the first page explaining the main points about tuning. Looking off those stats, I would recommend adding more brake pressure (how much depends on your personal preference and if you use ABS), and maybe stiffen up the rebound settings and soften the bump settings. If you want more turn in response, I would add more negative camber, I usually go around -3.5 (front) and -3 (rear). I’m not an expert on toe settings, but usually I don’t add front toe, and don’t go above .2 rear. Since I’m not a tuning genius, I would recommend checking other threads for explanations on why you would or wouldn’t make these changes. You might not be able to change the differential settings because you don’t have the race differential installed, which is in the transmission group in the upgrade shop (it doesn’t cost any pi). TBH, if you’re just going for the achievements I would get a few of your friends to try it out and give you feedback. Personally, I haven’t made a penny of my tunes (mainly since they’re mostly horrible one and done tunes for career -.-), and I’ve given up. Hope this helps to some degree.
One solution, if you and a friend can spare the time is to set up a multiplayer series of drag races using each others tunes and paints, you could reach the required daily usage level within a few hours. At least usage would be guaranteed with this method. Set maximum number of heats and each heat will count as 1 use 
What he said ^^^ or if you have a second profile you can do it yourself.
You need a lot of uses per day (cant remember how many 200ish) and you need to do it 2 or 3 days in a row to get them all. Think that maybe the paints too.
Can do it yourself in a second profile on your own. Just go multiplayer and do drag racing with settings at 10 heats and 5 second end timer. With the correct paint/tune .
Elastic band the throttle and tape down the A button, and all you need to do is hit the A button every 5 or so minutes as heats will restart automatically.
