Thus why my car is being tuned independently by a Subaru master tuner on a dyno via a 6-8 hour long session. There aint no "one size fits all" approach for my ride - I wouldn't take the chance.

Draco is in Ohio and Ryan86 is in South Africa, so I highly doubt that you tuned either of their cars on a dyno in person from California. Likewise Draco doesn't have the knowledge to read his own afr maps, he sent it to your company for review which means he has to take your word for it rather than being able to tell for himself if he was too rich or too lean. He also doesn't appear to have the knowledge to tell what went wrong with his car without consulting a mechanic, whereas I can pretty much rebuild this car in my sleep. It's easy to tell someone who doesn't know much about cars "nope it all looks good to me" as they're none the wiser. So Draco I'd love to see those records you said you sent in for review to Delicious - there are plenty of knowledgeable people on here who could tell you if the tune was the root of your problem. After all - the boost you were running is MORE than safe on this engine.





Don't forget that superchargers rob power from the engine to make power... so the same boost you use on a turbo car is not going to give you as much power with a supercharger. Likewise 12psi on a turbo with a 50 A/R vs a turbo with a 70 A/R is going to make a huge difference. We have no idea what the equivalent A/R is for his supercharger since it's not exactly built like a turbo.



And what do you consider "reasonable" to fix the motor when you spent $5k on a supercharger kit? Forged pistons - $650 (http://www.ebay.com/itm/261384876871...%3AMEBIDX%3AIT), new rods - $1500 (http://www.ebay.com/itm/391067640449...%3AMEBIDX%3AIT)... You could completely rebuild the motor with new internals that can handle 500+ WHP daily for less than you spent on your supercharger. Seems reasonable enough to me.
A sample size of two doesn't prove shit...Furthermore, no amount of added pressure/forced air into this engine can be deemed "safe". Plenty of people have grenaded their engines for various reasons. Any time you boost an engine that isn't built for boost you're rolling the dice, even more so when that engine has ridiculously high compression.
