So what was the total cost for ECU and Exhaust? Are you installing everything?
Do they make any statements about limiting the life of any drive train components, such as transmission. What about Valves and other engine wear? I have enough problems with this car, I don't need to create them.

As for competing with T5's, I have seen comparisons in 0-60 times and the GLT, in spite of less horsepower, was comparable to a T5. The real difference was felt in mid and high range acceleration (there was no competition once the T5 was rolling. The comments about drivability of the GLT LPT have always made me glad to have one. Overall I'm pleased with its performance. If I can break the wheels free on a GLT how much more power can you put on the road. Is traction control that effective or does it limit power. I would think the only way to put more power to the road is to add more tire area and make suspension modifications. I'm not trying to knock T5's but see if any of this is remotely true.
