My son's Daytona is fine cold but when it warms up it looses power above 3K rpms. Basically when the Turbo kicks in. It will barely pull a hill and has a top speed of about 25mph if your lucky according to my son. If you let it cool down it will run good for a little while.

I have not looked at it yet but other forums have threads with the same problem but nobody stated they found the answer.

I'm going to start with the basics Fuel Pressure, Spark etc. but is there a common problem to hone in on?

thanks in advance.
