I have tried to no avail to figure this one out and i know that there are quite a few smarter folks out there than me. Question to all those with tuned ECUs. I have the Evolve/Powerchip and while i feel a real nice boost down low and surprisingl(compared to some of the others) good boost between 4k-5k. However, Frequently i get a lag between 3.5-3.7k. It feels like the car is pausing to take a breath before the sprint to redline. Any suggestions? Any pointers on were to get my dealer to start? They are supportive of my need for speed.
