Base line Dyno plot for review and comparison before I decide what else can be done and what makes a difference.
Seat Ibiza PD130 2003
119500 miles, engine standard, head never been removed standard PD130/150 injectors.
GTB2260VK Turbo on Cast and welded manifold (Nearly 40k miles old now)
Miltec Turbo back exhaust.
Forge Front Mount Intercooler.
EGR disabled (Since 60k miles)
SMF and uprated clutch.
Air Filter: UFI paper, new.
Tyres Hankook winter icept 205/50/16, relatively new, 28psi very cold.
Fuel:Regular Shell (Fuel saver), no additives.
Car well strapped down as ice was defrosting from the car and dropping water on the tyres and rollers causing traction issues.
Temp inside was about 4 degC
Dyno run in 4th gear.
Dyno run is slightly longer than a 4th gear run would be.(2 gears to go)
Note tune is designed for standard Dual mass flywheel and clutch which is why there is scope for improvement on torque between 2000 and 3000rpm. I am not planning to change the tune util I make a couple of other changes.
I took some VCDS logs during the dyno run and have amalgamated the data.
Here are the amalgamated results:
Note cam sync angle where torque dips! Cambelt is close to scheduled change, but tensioner is reasonably set.
Here is the Full Original Dyno plot from the MAHA Dyno:
Note VCDS rpm is reads less than Maha by 200 rpm at max speed.
Here is a video of one of the runs to see the smoke level:

This was inside a closed building in which we did 4 runs, and as it was cold outside the doors were not opened and no-one felt the need to have them opened. Engine was loaded up from pretty much idle speed upwards.
No doubt there will be arguments about the 58hp losses. The facts are this was on a Maha Dyno which is twin roller, and was strapped down quite hard as there were traction issues. I can see from the logs the engine was idling on Dyno overrun and we can see from the video there was no brake trickery.
As a comparison for where those figures are I would estimate a vcds 1/4 mile would show a terminal speed of 94 ( A litle over 1250Kg plus deadweight driver)
I hope this info is of use to you all, and even more so if my next couple of mods work. Any questions just ask.
Merry Christmas to you all!
