Stock class down here must be different from where your from. Class 1 street diesel is programmer, intake and exhaust with stock original turbo. Class 2 is the same but with modded fuel enhancements. Class 3 is modded/aftermarket turbo like stock turbo with a bigger turbine/compressor. Class 4 anything goes. The price for what they do to the stock HE351 is ridiculous for 25hp gain and 100degree drop in EGTs. That's $50 per 1 HP...
