there is a difference between a former factory technician and a shadetree mechanic...
guess who's who in this case...
BTW, unless that compression test was performed by a subaru factory technician with inspected / calibrated test equipment, how do you really know what's accurate?

i love this stuff. those compression #s dont indicate anything. i have seen the same thing for years now. if #3 had 90psi i would be concerned. also its pretty funny that your sweeting an engine problem then decide to hammer 21 psi to your stock pistons.
what was wrong with the intake valve? so far since i have been around subarus i have yet to see an intake valve failure. oh but wait, that awsome meth and water your putting in your intake is corrosive. what is that going to do to your valve seats.not going to make a good seat.
what was the leakdown % i have seen perfectly even compression #s and when a leakdown is performed found one hole at 30% and the others normal. but when the engine was pulled 2 cylinders had broken ring lands.. on a stock ej257. both compression and leakage tests are guides.
what ever bla bla bla
i wonder what kinda guy would want to tune an engine that is supposed to be damaged. thats what i call a hand grenade.
lets take the engine apart and see the truth.

What Benefits are there other than the above?
It also has the effect of "steam cleaning" the engine from the throttle body to the exh ports. No carbon buildup on the backs of your intake valves, and the domes of your pistons stay MUCh cleaner. Which means MUCh less chance of "hot spots" which cause detonation

Doesn't water/meth injection do the opposite?? All the research I've done concludes that it cleans the internals -

Well not everyone can rebuild an engine at the drop of a hat. Plus, a tune that doesnt knock is better than a tune that knocks, no? The compression down is a bummer but if it still has life in it, might as well drive it (especially if money is tight).

if you haven't noticed a pattern yet, keep looking at threads..
mine was taking to TunerX a long time ago and he claimed that the car was pulling way to much timing. but when taken back to the shop, the shop found no timing issues...

no not everyone can just do that.. but why would you tune a car that has internal issues? By doing so wouldnt the tuner then take resonsibility for the car (to a certain extent), but why would the tuner take that kind of risk when he knows its not running right?

and a true "tuner" would say, "take it back to whoever tuned the car, they will help you with your issues"
