I own a 2003 Honda Civic with a aem v2 intake. But even before I but the intake on I was topping out at 100mph. I am trying to figure out why is there some type of restriction that could of been put on by the preveous owner. My old car a 1999 honda civic dx hatchback toped out at 110. But this is a more powerful engine so whats the problem.

welcome to the forum backdragoncivic; enjoy your stay. I have a 02 civic 1.7 5 spd, I have gotten this civic up to 120 level fwy, with more to go. stock. do you know if the transmission was modified to get down the 1/4 mile quicker. Is there any other mod''s besides the intake. Intake should improve the breathing of the engine to perform better.

No I dont think that someone would modify an automatic trans. Or even if they could. But thaats were it tops out before and after the intake was installed. I use synthedic oil and I have 73k on the odomiter. I am confused of why it just stays there like i am crusing. What can I do.

when was the trans fluid last changed, are you checking your fluid level when the trans is cold, and what type fluid are you using? And do you have stock wheels and tires.

Dont know if a governor came on those model civics, but I know a cpu swap removes any that you would have to increase power/performance.
