Hey guys, started truck the other morning and got this awful loud chirp or squeak. Dod has been deleted as well as vacuum pump. I have removed serpentine and turned truck over without fuel. Knock and squeak was still present. Removed valve covers and didnt visually see anything wrong. Could it be a flex plate or bearing? And motor runs good with vacuum normal.

I would say its restricting you big time. Before blower I had vvt delete, stage 2 tsp 5.3 cam in 6.2, 1 7/8 headers no cats, into borla. Made 421 @6200 hp and 469 tq at 3700.
36 hp and 68 lb ft of torque diference on my 2014 6.2 between 87 and 93 on dyno. Pulled timing like crazy with no external load. Iat was 94 degrees. The 6.2 is not much better on 87 than a 5.3 on 93. After cam and headers it did 435 whp on 93 and 391 on 87. Its got a whipple now. Done a lot of pulls testing the fuel. It also has e85 now
You will need to get the adapter to run a head unit with the bose speakers. The speakers have an amp at each speaker so you cant run your amplified jvc wires to them. Its why you dont have the proper covers
How much boost you running and is it factory cam? Headers? A lot of shops go consevative on the tunes do to ring gap. Wouldnt be surprised if you had a bunch of timing pulled so the meth didnt help much. It helped on mine a lot
Yo guys, I have a 2014 Sierra Z71.
Trying to figure out the widest 33 inch tire I can put in the rear with aftermarket wheels. I dont want them to stick out past the fenders more than an inch. Would a 325 be doable with the right offset? Factory height. 600 whp. Need traction
Mine was loud so I had put a qtp twintronic screamer muffler with electric cutout in line with it and just opened cutout to straight borla. it blew the twintronic apart with the boost on the dyno. that's when i went dual. Qtp replaced under warranty if you want a muffler. 3.5 in/out. you could slap any cutout on it. cheap
Did you get the xr1 installed. I had the xr1 15 inch with headers no cats on the factory 3.5 pipe split to duals. It was a drone monster. Now i have 3 inch duals with large magnaflow dual in dual out. Doesnt drone as bad but is more raspy at wot. Thinking about going dual xr1. Can hear cam fine with magnaflow though
