OK. So I installed the Banks CAI kit last year Christmas. From the time I had installed it up until now it seems that at part throttle there is nothing more than a delay in power almost like its bogged down and a great deal of noise as you can hear the increased amount of air coming in. At full throttle it screams like a banshee and has no problem getting up and going. Since Feb. I have contacted Banks 3 times by email as they would not talk to me on their customer service line that Summit gave me the number to. I have yet to hear from these people in any manner and not sure what I should do next. My thinking is that I need to get a programmer. However, I don't want to spend a lot of extra money on something that is not going to resolve the issue.

Sounds like you have a leak, and it is sucking air after the MAF, check your connections, rock the intake back and forth and see if the couplers move a great deal or not. If you are all good, then I would look at a different intake, programmer is going to change anything. Unless you get a wideband and log your A/F ratio with LC1 and a tuning program like EFI Live, you won't know for sure what is happening.

You know this was supposed to be a simple bolt on and I have never had a problem with anything like this before. Not really up on the technology thing and may just end up putting a different CAI and mail banks kit back to them with a letter thanking them for selling quality garbage.
Are you familiar with Black Bear Performance? I hear they send a logging device to do a custom tune specifically for your truck. Only problem I have with this right now is that I have not completed things like the exhuast work and they say you need to have all performance mods completed before the logging.
For now I will re-check all the connections. Thanks for the help.

i have an AEM CAI on mine, and sumtimes i get the same effect, untill i hit the pedal enough to get the tranny to kick down, then she takes off like hell lol , its probly not the banks, banks has been killing the diesel market for yrs now, im pretty sure they know what there doin, also if i have my a/c on u can forget about takin off quick lol, im gunna start lookin into other possible causes myself, plugs and such, ive only got 50k on my truck so i couldnt imagine too many things being worn out to cause the lack of power

this is true banks is at the top for the last few yrs especially for diesels let me know how it goes i just found they have a gas cai n in love w it plus its banks not bs injen or ebay models u pay for what u get i think i assume u got it from summit ? lookin around for mine but 2011 there aint didilly for it yet : ( have u heard anything on their new programmer
