When you do the back to back, port the **** out of the Megan because it is going to need it!

Also if you do a back to back please get a nice 02 dump like the Shearer. The others are not that nice and have some problems. I would like to see a clean back to back on two 02 housing that are well designed. By the way, Mike at AWD did a back to back and picked up 25hp

Hands down the Shearer 3" is a much better quality piece, and will perform better. The map has some problems that I'm not bringing up cause MAP get upset.

Someone messaged me that too about the MAP dumps, which Im glad they did because I was set on getting a MAP dump. The other options are Shearer or JM Fab, probably the Shearer as thats the one that seems to get the most praise.

Shearer 100%. They use the JMF flange so you get 100% quality piece. I don't think JMF has a 3". You honestly want a 3".

Wow you've really got it out for me lately huh? Please bring these "problems" into the public eye so that I can address them properly. A quick search regarding my product on this forum yields nothing but positive reviews. I am fully aware of your opinion regarding the 3d contoured turbo outlet flange, but until you prove that it makes any difference whatsoever it will remain just that, an opinion.

I would be very interested to see the message you were sent, but I'm not going to hold my breath. In any case, I personally guarantee that you will be completely satisfied with any MAP product you purchase. I'm not claiming to be perfect as we've had a few bumps in the road, but we have and will continue to stand behind our product 100%.

i had a epm dump and changed to a buschur o2 housing, believe it or not it actually spools turbo quicker and i am running a fp red, i am sure dumps have good gains on larger turbo's though.

From what I've heard the EPM has some "restrictions" (which is why I'm switching to a MAP in the future) and would you like to provide a dyno sheet or log from said gains?

My response was somewhat sarcastic sir as I'm running our 3" O2 eliminator downpipe on my personal car with no issues whatsoever Additionally, BLKCarbonEVO has said himself that he doesn't run any MAP products so my thoughts are that the "issues" he refers to are nothing more than theories as I outlined above...

Our customers are very satisfied with their MAP 02 Dumps, the fitment is great, the quality is perfect, the price is just right and the "butt dyno" says the gains are very good. I'm currently swamped with cars at the shop but when I clear some of them out I'll be happy to do a little testing on this matter.

Thanks,

Chris@ASAP
