I just installed megans headers and the ebay 02 housing in my car. My prior mods are a 255 walbro, aem intake, and a turboback. After i put on these new parts my boost is all over the place... in 2nd gear it goes from 20 to 17 then in third from 18 to 16 and so on. My car is definately alottt slower now. I just lost to a stock sti the other day and before i would be right next to him. Also, everytime i put the manual boost controller in and set it to 18psi all it does is FUEL CUT like crazy in 3rd gear (at 6krpms) and 4th gear. So i talk to some people from devo tuning and they told me that the o2 housing are useless... but i saw the o2 housing and it looked alot better flowing then the stock. So i dont know wat can be causing this loss of power. And if i port the stock manifold/o2 housing wat makes it different from the aftermarket mani/housing? So im planning on taking of the aftermarket headers/o2 housing out soon cause this loss of power sucksssss and im also putting the stock intake back on cause im not feeling now extra power the aem one. I need input from you guys...Any Advice or help? Thanks

 

come on guy, if you've read any of the posts ever on this forum, you'd have seen the numerous times people have had this problem, and the answer always is, you need a tune. slap all the parts on you want, you're not gonna get their full potential out of them till you get her tuned to accomodate your mods. and the correct word is loss not lose.

 

Stop messing around and get a tune.

 

Sry LOSS.... Yeah but all these people are saying they installed these and they got all these gains WITHOUT a tune and am i suppose to be experiencing a loss of power from these hp adders? And sry but i dont have $500 to slap down on a tune everytime i put on a new mod.

 

This is almost silly... get the car tuned.
