My FreeScan Log

[Invictus005]

Hi forum, would someone be kind enough to take a look at my FreeScan logs and see if anything is out of place. Especially during the several WOT pulls. Thank you so much and greatly appreciate it.

Do you have a specific engine performance problem, and if so, what is it?

Do you have fault codes showing?

[Invictus005]

No codes are showing. The car has been very consistent in performance for approximately two years of my ownership, so this is not just me getting used to it. And then one day it seems to have lost some power. It doesn’t pull as hard as it used to and it’s noticeable at higher RPM range. This is a 1991 Turbo SE with S4s chip. Everything seems to be in order except it feels underpowered.

It’d be handy if you told us what year/model. 

Do you have the engine-driven charge cooler pump, or an electric one?

[Invictus005]

Electric.

And the year?

What is your boost gauge supposed to show at WOT?

looks like its boosting to the chip's limit
