lol thanks blue, exactly the point i was trying to get across. The Bumps do end up itching sometimes. :P As mentioned only reason you might be ok is cus your running rich as **** hence the point he made of washing your cylinders( aka wash down the crosshatch you need for your oil to stick to to keep the cylinder walls/rings happy). If you want to take the risk and replace a motor that you dont have money for because you obviously cant afford a tune/wideband ect. then be my guest. We are just trying to save you the hassle of going threw some of the **** most of us already have.
There are alot of guys on here that im sure would be willing to tune the car for you. So buy a wideband and do it right. Oh btw when the car is actually tuned because imo its currently not, you will be quite happy with the improvement. Basicly if your running say 9:1 afr right now to keep the car happy your losing power and washing your walls, if your running 12* of timing your losing power, if your knocking your losing power and potentially gonna blow up your motor. So without a tune most of your mods as useless and you probly gained nothing because of the 3 things just listed.
