This kind of awkward to ask.. what's a typical donation when requesting a Tephra mods rom?

 

I think he thinks $1000 is a round figure. On the other hand, who would know what some one else paid?
The guys tuning multiple cars should be paying more but the single, stay at home one car tuner, well, first of course $1000, or what >25, < 100?

I'm as in the dark as you.

 

As much as you're comfortable with.

 

what he said! ^^

 

fwiw, I gave 100usd and will give more in the future.
Your stock ECU gets lots of after market features and high resolution maps. Ask yourself how much you would spent on those features if you went the after-maket route.
