There all within 5 psi of each other. I wouldn't be worried about it at all.

That's fine/good.

Check your oil is fresh and the level is correct, battery is fully charged. May increase your figures very slightly.

But as a above less than 10% variance and all is good.

I assume the cam shafts are stock?

Oooh

Ye all stock internals just a few bolt on mods.

Have see others compression results at over 150-160 so thought mine may be getting a bit tired.

Thanks for the reply's greatly appreciated

Just one more thing why the big difference between the dry and wet results?

[Ben C34]

Was the dry test cold?

[pittyoo]

Yep both tests where done cold

[admS15]

The test is supposedly more accurate and meant to be done while the engine is at normal operating temp.

[pittyoo]

Ok may be worth doing again then ?

[Ben C34]

Maybe. But I wouldn't bother.
