So I wanted to make this quick review on @Jason@dizzytuning E40a tune with the turbosmart 7psi wastegate. I noticed that not many people talk about this really and I am sure there will be someone else looking around who is not ready to upgrade their turbo but want to get as much as they can out of a stock turbo like me.
First thing first I want to say Jason from Dizzy has been amazing at answering all my dead end questions and being a good sport lol this is my 2nd tune from him and I am still very impressed. My first was E30 and that woke the car up a good amount and I was very impressed. But my problem was ( since I drag race the car, and yes I know that not what its meant for but I'm different) that the turbo would fall off too quick and I really didn't benefit from running the engine out farther than 5k or even 5.5k. So that's what I was figuring to get the upgraded wastegate to hold the boost a little longer. which it did and now I can feel the pull all the way to 6k and even redline. Now it didn't really add much for power but the boost ramps in much faster and stays longer which in the drag world is a good thing. I will say using the Cobb estimated HP and torque I did see a small improvement in both numbers from the E30 to E40 tune. I know those numbers are rarely accurate but I was just looking at the difference.
Installation was fairly easy except for the dreaded heat shield and I am too lazy to remove the coolant lines. so yes you guessed it, I didn't bother putting the shield back. That's on me. But once that was out of my way the rest of it was fairly smooth and east to adjust. Using reference from Jason's video I was able to set preload to the desired amount and it all seems very spot on. Put it all together and flashed the tune and went for the first drive and sure enough the tune seems perfect. To be honest if I knew more about this earlier I probably would have gone straight to this tune and skip the E30 all together, but i don't mind helping him out a little. I still have to run 100 miles before I send in the datalogs hopefully before the next track day because I'm curious on what improvements its made for launch and on the top end. If y'all are still interested on how its all going I can post my times and answer any other questions anyone has. Hope this helps
