That's the same company that said it could remove any sensor you wanted, like EGR. Does it seem odd that they can remove any sensor and NOT the VSS?? Also If you need to change anything you need to send the ECU back to them for tweaking. NOt a real effective way to fine tune the car. I Would also ask them how they see so much boost with a 1 bar map sensor.
Best bet is to get the flash, if you can. Other wise MSD and some other piggy back FMU. That will allow you to dial things in between runs, or passes and will not take over a week to see and gains or losses or no starts
Oldsman why can't you get the flash? no one will do it or something else?
