For the new 6.7L we have yet another new turbo design. This turbo uses electronically controlled vanes inside the turbo to adjust boost levels and allow for quicker spool up and ability to precisely control EGT's. With the boost fooler installed you will see drops of 125 degrees on a stock truck (considerably more on modified trucks), up to 10psi peak boost gain and 6-8 psi sustained boost gain. This is the ONLY product on the market that is plug-and-play. There is no cutting, no splicing and no guessing. Simply plug this device in enjoy it!
