Found out the compression tester that I bought was defective. Lucky ME. After using the new tester my readings were 235,240,235,240. I'm so relieved. I guess thats the reason I did not notice any performance lose.

haha that exact same thing happened to me two weeks after I bought my car. It had 2k miles on the odometer and read 100-100-130-115. I just about sh*t my pants.... to broken compression testers

 

Damn happy to hear that man, and see you were just about ready to spend all that tax refund!!

I just did a compression test on my 94 GSR (125,600 miles)
I got 210, 205, 200, 205

I did not have the throttle plate open - how does this affect the test?

Safe to go turbo? Should I get a leakdown test as well? Can I do that myself?

Thanks for your help

 

no the compression readings.

open throttle/closed throttle will affect readings.

closed throttle will give you lower readings.
