Does a chip on a 1.8 yield substantial gains BEFORE the turbo kicks in?.....
if yes, how does it achieve this? Isn't it just a naturally aspirated engine until the turbo kicks in?
So at most isn't it just optimizing air-fuel mixtures before the turbo kicks in? I wouldn't think that this would yield much....sure a slight difference maybe, but not a huge difference.
Am I wrong here? How does the chip do this pre-turbo?

that's what I thought.........so is this guy imagining things?......
check out some of the responses.....some seem to be arguing that there is some pre-spool boost and/or improved timing.
not trying to stir things up....genuinely curious...<ul><li><a href="https://forums.audiworld.com/a4/msgs/1186260.phtml">https://forums.audiworld.com/a4/msgs/1186260.phtml</a</li></ul>

this might give you an idea of torque output... it's for 1st through 4th, so just look at the first
peak.

The APR 93 octane proggy does have a nice increase in pre-boost timing........
(relative to stock) and it makes for a very nice driving experience before the mity mite K03 comes in.
In repsect, I also have the 91 octane program and its more boost dependent...the engine feels fairly gutless (compared to the 93 mode) before the turbo hits.
