stock, of course if you want to plan for upgraded turbos then you might save yourself some time and $ in the long run by installing the 555s now. But in terms of stock turbos, the JWT ECU will allow you to run them to their maximum output (with race gas). Depending on the octane rating in your state, you should be able to run between 14-16psi on pump gas and 17-18 psi on 100 octane. I have never seen a properly tuned (ie. ECU) and appropriate "octaned" TT have any problems beyond those inherent with increasing the HP and load on the car. Give JWT a call and see if you can talk to Jim or Clark Steppler ( he does the modifications on the ECU and is a real nice guy...smarter than hell). Good luck, Mark
