Well... I did acknowledge that such mods on a 248k engine were... well... a bit much.  The largest risk being the rod bearings, and really nothing else.  I also recommended he NOT run a larger WG spring.
  
For point of reference... my car made 325whp with that software and all the RS2 parts... no ping, and no toulene.  Another point... I use my car between 30 and 40k miles per year.  My car spent (with RS@ parts) a great deal of time at or near sea level... again... no ping.  This is also "just fact, and not speculation."  The only location where I had issues was in California, where the fuel was clearly not up to the task.
  
Further... I ran that same software to over 400whp (with a GT30R0)... with a wideband displaying an excellent A/F R... and still, no issues.  Finally... I ran that software for several weeks with a GT3071 turbo... and again, no issues.
  
Chris (fastvw) WILL be able to make that software work just fine in his car.
  
Dave

Dave:  I know Uncle  Bob didn't actually write the code.  I also "know"   
(believe) the two chips were not originally developed as a pair but have
 been "married" from two sources, e.g. MTM and Thomas Schmalz.   But
 that is not the point.  The point is the software is fairly aggressive timing
 and boost-wise, e.g. 317 whp running 10L toluene with 70 L of 94 with an
 RS2 turbo and injectors = about 396 crank hp from one of our club cars.

Put this together with the 1.9L WG spring and an engine with 248,000   
miles and I still contend its a receipe for a "bomb"/grenade.  As I   
suggested, either the "Pastore" software and a stock WG spring (which   
you agreed with) OR the MRC software and the 1.9 bar WG spring BUT   
NOT the "Pastore" software AND the 1.9 bar WG spring.

And on the issue of pinging, I bet none of the long-term users of the   
"Pastore" software live at sea level like we do.  The combination of   
aggressive timing, etc. and dense air just doesn't work as well as other   
places in North America and results in lean air fuel ratios that cause   
pinging at WOT. That's just a fact, not speculation.   

Cut the red wire.
