Just drive here and i will throw a DHP 1.0 pcm on with a few changes on for free. The only reason why DHP pcm's are so successful is because they offer the least changes over a stock pcm, once you throw a 3.4 pcm on and then tune, the least bit, you are going to be happy.
do you also do custom tunes?
