hey guys i recently bought a MAP o2 eliminator downpipe to replace my megan o2 housing and downpipe. i have an fp red at like 26 psi and a tune. i was just wondering if i will be ok or if the car will have boost creep. funds are a little low right now so i need to wait for the tune when i get my intercooler and grimmspeed boost control solenid. what do you all think?

 

I'd stay off it. Mods on each car react differently as far as a/f and temps go. Wait for the tune.

 

My car ran like **** when i put the o2 dump in before i retuned it.

 

damn lol alright well then i will just have to wait until i can throw everything in at once and get the tune

 

From what I heard you can do you the exhust side(ported manifold and o2) with out a retune. It's when you do a ported intake manifold and TB is when you need a retune. The intake side is where you are forcing more air in the motor and you need to and more fuel so you don't go lean. The exhust side your just letting the exhust gases out quicker.

I did both of these to my car and it runs fine. Pick up a few more pony's by doing this. But it is always good to get a retune on anything you put on your car. But you don't have to really for the exhust side.

 

i thought that as well. i may do the install but i am not sure yet. thanks for the advice.

 

i dont recommend it. my upper o2 sensor failed a couple of weeks after installing the o2 dump. the a/f was way rich after the o2 dump install

 

Which one did you get? Was it the VTA or the recirculate DP?

 

it is VTA...i am probably getting a tune shortly after i do the intercooler and MAP o2 eliminator downpipe...i have the do my grimmspeed bcs once i get to the shop
