Normal boost graph

estebanvdt · Jun 22, 2018

Hi guys, looking for your feedback. Currently running a tvs blower with 80 mm pulley, would these boost fluctuations be normal? I’m guessing these dips in these blowers shouldn’t happen, could it be the belt, bypass?

Cam timing changes

Thanks for your input, so it may be due to the tune?

yes but every tune will advance or retard the cams. Also depends on where its tapped for gauge. If its one runner intake valve opening and closing will have effect on boost reading

Need to see more of the graph... How many psi is the variation?
