[QUOTE="wasabigrinch, post: 1193926, member: 23188"] Last week, I let Flowmaster's research branch borrow my truck for a few days to do some airflow testing for a CAI they are building. In exchange for letting them borrow my truck, they put offered to put on a catback exhaust system and a new (not yet released) delta boost module. First of all, I love the improvement to the truck. The delta boost module is a piggyback setup on the stock airflow sensor ([URL="http://www.flowmastermufflers.com/performance-tuners/18103-flowmaster-delta-boost-module/"]more info here[/URL]), and it adds noticeable pull. Turbo lag is lower, and my truck now chirps tires when it shifts into 2nd with traction control on. I'm also really happy with the exhaust they chose. It's quite mild, but produces a bit more aggressive sound around 3 - 6000rpm, and has minimal drone compared to other Flowmaster setups I've heard. Here's my concern: The delta boost module claims that it can add up to 4PSI of boost. If I floor the truck in Sport mode and module in MAX mode, I'm seeing 28 - 29 peak boost while running 91 octane. I'm seeing this from the calibrated boost gauge in the module's app... the boost gauge in the truck appears maxed pretty early in the acceleration process. The Flowmaster guy said that I shouldn't be concerned, stating that 'these motors can handle a lot more boost'. If something did go wrong, apparently the mod is completely untraceable. That said, I'd rather not pop my motor. Any insight on what is 'safe' to run on these motors? Any idea what the peak boost from other tunes typically is? Thanks in advance! [/QUOTE]
