you are running really rich, dont wash all the oil of your cylinder walls

Since your clueless...spend more money and have somebody check it out. Hopefully it just need to get dyno tuned and keep it from running rich.

im not stupid it just that some one else owned the car and screwed a bunch of stuff up and ive been fixing them as i see them just wandering if there is something im missing. this is my second 240 and first sr but i have modded lots of dsms im not new to turbo cars i curently own 4 turbo cars. i just want some help from other do it yourselfers. if your comment was misunderstood im sorry but it came off very cocky and a bit prickish fliprayzin. but i do think your car is very nice still.
