Ok the problem I'm having is my car bogs horribly after you take it past 2 grand. I had a similar problem but last time my vaccum line had dirt in it and I just blow it out. Now there's no dirt and swapped the map senors but no luck. I plan on taking the voltage of the tps but I dont think thats the problem because its identical to what happen 2 months ago. Now some insight this did start to happen once I removed the amps from my car. My friend suggest a retune but there's no creditable shops and I don't want to mess with it since it was tuned by inline pro. Any help is appericated.
