Not against the 2300 at all. I am open to the input yall have to offer. What would be there difference between running the 2650 at a lower psi? To put equatable power down to the 2300? -what would take 8lbs for 2300 take 5lbs for the 2650 (random numbers for psi) this is genuine curiosity for an understanding perspective. still waiting to hear back from Texas Speed and GPI to see what they would recommend but would like to be as informed as I can to know and explain what I am seeking. So again appreciate y’all’s time and replies.

Thank you for the indepth post. I have been researching alot of what you had written. More so looking at the low lift cams. I did take your advise and moved away from the Whipple and looking to the TVS 2650. It has been back in forth with the SC in the Camaro and corvette forums, but more so of how much power they could obtain. I am more concerned with just achieving my goal with reliable nice sounding SC who can put consistent power down. From what I read low lift cams tend to move the power higher up the RPMs. Not to big of an issue because I would imagine the SC would compensate power down low just fine. As well as with it being paired with a SC create unrealized HP. I would imagine not so much given I would not be running more than 8 PSI, but its still something I am reading into. Plugs, Wires, Trunnion are all on the list. As well as my transmission service is due for a refresh and will be taking the to do what is needed then.

2015 Sierra 6.2 2WD 8 Speed. I am split between Supercharger and Cam to do first. Looking a semi driven vehicle with a power range of 500-600 WHP Supercharger: I am split between the 2650 Magnuson or the 2.9 Whipple Supercharger. With the supercharger I read it would be best to upgrade to the LT4 Injectors and an HPFP. - I see a varying of prices on LT4s also different fuel %. Are they all the same product just marketed at different? Also what would justify a higher fuel percentage? Running E85 would also be a consideration to add to the update. I have it available all around. CAM: I am looking at a Stage 2 SC Cam. But this is where I am still trying to get my education in Lobe/Lift/Duration. Also during this process would be doing a DOD/AFM Delete. I have been reading several posts around regarding others builds and questions. I have gotten some direction. I will be keeping stock headers or upgrading to something with Cats. I am looking for a mildly loud exhaust. MBRP is currently on it. Thank you all in advance.

Been researching through the forums but it seems not to many have dropped their truck running a 305 tire with a 4/6. I was curious to see if anyone has experience with a a wheel set up of 305/50R20 - Rim - Black Rhino 'Sierra' 20x9.5 Offset 12. How would this work out with rubbing and drivability.

I have a 2015 Sierra Denali with the Magnaride. It is towards its end of life and set between two options. 1. Replace the Magnaride with OEM system and go about the days and drop the rear to match. 2. Switch to a dead system and commit to a 4/6 drop. I have a few questions. Are there recommended kits that delete the magnaride. I have found 1 in Canada that runs 1500 in Canada. Seeing I am in Texas not the most ideal location. Also what kits are out there for the 4/6 drop. If anyone wants to send Pictures of a Sierra on 20's with the 4/6 would help. I am leery to do a drop with 20's as I am not sure they will fill the wheel well properly.
