i really dont wanna pull the intake off and have to put the stocker back on cause it definitely makes more power with the LSXRT no dought but the drivability isnt there.

Do you still have your stock intake to see if the idle problem goes away. As you know, it doesn't take long to swap intakes. Just a thought. But I would definitly either buy HP tuners or find someone who can log your truck sometime. HP tuners was the best purchase I've made so far!

If you want I have a 99-02 dbc BOLT on TBSS intake complete I could trade you plus cash on my end (Rails/regulator/90mm t-body)

Ooooo hi there. Sorry to hear about your fast garbage

Mine is "fixed" sitting in the box. Im such a non believer in the FAST products i will probably never put it on. My buddy got one for his 234/239 111lsa cts-v. Driveabilit is **** after two seperate tuners. They make great efficent power at WOT but driveabilit is hit or miss

I would try another tuner, amd hope for the best
