Well got another litre through the engine today and the engine is screaming in the truggy thats for sure, i also run the jammin 21 plus engine and boost is running on a close par thats for sure, run times will be tested in due time thats for sure but i wont hit the track with it until the mech pinch as all but gone....i have learned my lesson and with 3 other engines to choose from im in no hurry thats for sure....the picco 2046 pipe is an extrelely thin pipe that dents very easily, i tryed running one on my picco 21 plus and didnt like the pipe that much so im sure i will track test the boost package in the future but for now im happy with other pipes i have to run with it....
