At least the shop is willing to do something. A law suit wouldn't even be worth. alot of wasted time and money when that time and money could go towards VSR offer. unless you obviously absolutely knew it was the tune then yea law suit. Being on the GT-R life alot i see so much of this happening because no one keeps a stock GT-R it seems. Picture massive builds. 100k lost because of bad tuners or shops taking short cuts. But that being said most of those guys provide pictures and proof on their "call out vendor threads" So this does suck. But i would feel better about having the option of vsr building my engine. If they warranty their work and stand behind their built engine then why wouldn't you take the offer regardless of trust? I mean what other options do you have? What route are you going to go now? You have to move forward.

It's apparent there were mistakes made on both sides. Finger pointing is doing nothing to get your car back on the road. Introducing a 2nd tuning shop just added to more fingers in the pie. Infidel it was up to you to do your do diligence before you put your Z in an independent repair shop. Seems like your not getting many other people steppin up with complaints about the work from SR. I think everyone on this site will agree when you ramp up the power you had best prepare for a situation like your in now.
Either make peace, go have a beer and take the fig leaf offered or cut the cord and move in a new direction. If it was my car sitting in the driveway I'd sit down with SR and get it in writing what he is willing to provide. I'm sure if he rebuilds your engine he will stand behind the build within reason. If your standing on principle of him admitting fault you may be standing for a long time.
Take him to court?? seems like throwing good money to bad. You have a 50/50 chance to win and you'll spend too much time and money to gain personal satisfaction. Get SR to put an offer in writing post it & we can help you decide if it's fair & reasonable.
