Hello
I have a 07 Dragon 700 with a boondocker turbo on it, I run with egt's and an o2 sensor, the turbo is a boondocker racegas setup with the ada and the tunnel dump exhaust, it is running on straight VP111 at 6.5 to 7.5 pounds of boost. the symtoms are as follows: the machine starts great, idles great, at half and 3/4 throttle it seems good, but as soon as you go to full throttle, it runs like crap, coughing and sputerring. At 3/4 throttle under light load the egt's are at about 1150, as soon as you pin it, the egt's drop to between 850 and 950 and it misses badly. O'2 sensor shows an unusually high reading of 18 to 24. This machine has run awsome but this started as an intermittant problem and has gotten worse.
Im scratching my head
thanks in advance
