+1 - cold weather LOL - Techron will take a few thousand miles to clean up the inlet system. The only time you might feel an almost immediate effect is if your injectors where dirty - cleans them very quickly.

 

Irritated some stuckup @$$holes on the 204 forum by pointing out the difference that atmospheric conditions make to Dyno runs.

I read that thread. I wanted to chime in and say "stop being dense!" but I decided not to. It's really not that complicated to understand.

 

Wish you had! - They are dense!! Obviously never been out of puff at high altitude.

 

My car has 88k mi and was NEVER treated with any fuel detergents, so yes, i think i was feeling the dirty injectors being clean off for the first time, in a long time (LOL!). Thats why i was feeling such a dramatic difference.
It was about 60 degress F with the engine all warmed up already, the car just wanted to go go go!

 

You probably had dirty injectors.
