I bought my '11 coupe from an estate sale. It was claimed to be bone stock, but I noticed the boost gauge pegs under WOT. I assumed the gauge was just optimistic. To verify, I plugged in an OBD2 reader and did a pull on the highway and it shows I'm getting just over 14psi at high RPM and 11.5 at lower RPM. So the car is obviously not stock. And I have no idea what's been done to it.
I assume I can measure pulley diameters to check that they make sense with the boost. What else can/should I look for? I assume it has a tune, but have no idea who set it up or what they did. Are injector changes easy to spot? What else should I look for? Luckily, I've been running 93 octane in it (it's hard to find 93 around here, but I know of 3 stations).
I guess that explains my perception that this car has significantly more grunt than the Gen 3 Viper I had a year ago. I thought I was crazy...
