Vacuum Numbers for Hyd Roller Camshaft 212/212

[Silverttype1]

I've somewhat finalized my 5 year TR project -- although as we know it's a passion and a hobby that never ends until the money runs out! Inquiring what "true" vacuum number(s) should read for a Comp Cam Hyd roller 212/212 degree duration. I'm located in Florida...new motor showing a steady 7in Hg. of vacuum in park. Turbo Tweak Street 93 octane chip designed for 95lb injectors. Compression check on all 6 cylinders is 150lbs.

Thanks in advance!

14-16 hg here. Sounds like your either running lean or have a vac leak.

My 212-206 gets 19hg in Park over 17 in drive.

Guys thanks for your feedback...I assumed it was low--just wasn't sure, I will check tunning with translator plus...also look for a possible vacuum leak.

i would also verify the vac. with a second gauge just to make sure your getting a accurate reading

I get 14 in vac, with 236 Dur roller!

besides vac leak, check for retarded timing, it will show up as low vac.
and very high exhaust temps.
