Proper Boost??

just wondering what you guys get for boost....while cruising.

also i found that 32 psi seems to be the sweet spot for the hy35. At WOT my egt's actually drop a little from the intial jump due to lag.

Im getting...all with cruise control on!!

55 0 psi
60 4 psi
70 9-11 psi
80 12-15 psi
90 19-23 psi
100 25-29 psi.
110 32 psi (max boost)


are these fairly close to what you guys get?? This is all in mph as well.

I know at 100 about 9psi and at 120 about 10psi I get to 37psi if I put my foot to the bottom of the coal bucket. Hope that helps.

Speedo reading
55-4
65-7
75-12
85-14
95-17
105-25
115-31
120 34-36 WOT

I did them on flat road letting it level out at each speed. Tires throw me off 5mph and the 3.54's don't help. After 95 on the speedo I think the weight and non-aerodynamic full replacement created alot of drag.
