Ok i so me and a friend went to this shop and took a quick dyno run just to see what my car was laying down cause i beat his civic and he said no way and he let me run it for free since i have been helping him alot....Well first run got all messed up cause someone hit the overdrive button and i wasn't in the car and the guy that was noticed it at the last second so we scrapped that one....Then we ran it again and got 174.3hp and 180tq.....I figured somethin was wrong cause there is no way im running that much so we run again after letting it cool off for bout 30mins. and we grab somethin to eat come back and hook everything back up and run it again and this time we get 180hp 186.4tq......Know when i bought the car used the guy said that the guy had taken the engine out and worked on it some but i figured he just did a few fix it things and made sure there were no leaks and swapped the tranny cause it was in a wreck and damaged it cause i saw it....but is it possible that he did replace some of the internals? I know there is no actual way to check the internals unless i get in there in look, the only problem with that is i cant get in there to look cause were in our like 18th straight day of rain here...Any idea? and this is completly stock 98 ls with 16's up front not much else though did upgrade the transaxle cv joints with somethin a little stronger but still that shouldn't really do that much....
Edit---Just so you know this was a in car dyno...I'm not sure what the software was but It is the one that hooks into the obd-2 port and then he also ran 2 sensors off the exhaust.....Did it from 2nd and also 3rd...
