I've done a bunch of research on the JWT and most people claim to lose power due to heat soak whereas other people including my Osiris Uprev tuner absolutely swear by part.

I'm currently throwing on the mrev2 and 5/16" spacer, stillin z tube, K&N and motordyne ART pipes. Here is a graph of my cities annual temperatures in Fahrenheit if that effects JWT's performance: http://www.weather-and-climate.com/a...calgary,Canada

Also if anyone else has any ideas for some good bang for your buck mods that would work well with my current mods please let me know

 

This is one of those questions that have been asked/answered for years, yes any intake that contains metal will cause you to lose HP during warm weather due to "Heat Soak!" If you're tuner disagrees find another shop that has better/more knowledge.... Gary

 

What Gary said. If your shop/tuner is recommending something that will undoubtedly have heat soak and cost power loss that's not good. If they are supplying the parts then its more money in their pockets guaranteed. JWT Pop charger just gives you a nice sound. Stick with your Z-tube and K&N filter for GO and use the JWT for SHOW.

 

^ Your unedited post was better - this could have been answered by a simple search. There are several stickies/faq's as well as this guy to ask questions like this one instead of making another thread about this:
