ECU Tune Question
OK folks my car has been in the shop since the past two months. With all the work being done on the car i am getting the VRP550 package. Now I trust the shop but is there anyway to find out that the ECU tune has been done on the car. I can't remember how my car feels since i have not driven it for a while. I will be able to look at the pulley and filters, but the ECU I have no way to telling if it has been tuned.
Please any help is appreciated.

because then you can compare it to the mods you have gotten.
pulley alone will not be good enough to show gains, but if you have an ecu done it will show
Plus maybe a high speed run to see if you speedo is delimited now
also do not forget the track

**** I have not done a base line dyno pull.I only had the car for a week before I got ran of the road. If we hook it up to the star system will it say something in regards to the ecu tune.

An OBDII will show if it has a tune. Basically see if you have a large pulley. If so, then drive the crap out of it and datalog. If your A/F ratios, throttle position, O2 sensor data look good, then it has a tune. The O2 should show OFF after the tune.
