Just wanted to chime in that I got the discount and started working with Josh almost immediately (in fact, he answered a ton of my questions before purchase). I haven't quite installed my tune yet (will write up a longer post on exactly what I am doing), but wanted to say that Severn Tuning has been AMAZING to deal with from a customer service perspective alone. Plus you have a long time forum member who literally specializes in our rare cars and continues to be active in the community on a now 15+ year old platform and honestly, you'd be crazy not to take advantage of this group buy if you have been considering tuning your car.
I'll write up a longer blog post on my experience after I've finished, honestly I went a bit further down the rabbit hole than I had anticipated and I am actually installing an e85 conversion kit based on Josh's suggestion. Aside for "mo powah bab"y, e85 is nearly half the price of the 91 octane supreme unleaded where I am at (Califonia), so it was an easy call.
