14' 6.2 TVS2300 and Headers question
#12
Edelbrock is very conservative, I would grab the next size down pulley and put it on right before you tune it. If your injector duty cycle goes over 80% then swap the pulleys back and finish your tuning with the larger pulley.

Yes sir, that is what I'm doing. Have not talked to the shop yet, but they were planning on getting it in the dyno today. I haven't even gotten the truck back from this Upgrade and I'm already planning the next. Looking for a blower cam, heads, meth injection and possibly going ahead and forging everything. I have been reading up on the C7 mods, as there aren't many L86's built yet. Let me know if y'all find any,info out there, I would be interested in reading up on anything y'all throw my way. Anything from motor to transmission/transfer upgrades would be appreciated!

I see you have a 3.25" pulley, so I assume you are currently running a 3.5"? With my Edelbrock Eforce I thought I would see over 7PSI with my 3.5" but it barely hits 6PSI of boost at 6000RPMs on my 6.0L LQ4 running a ZL1 cam through stock manifolds and high flow cats. I was sure I would see over 7PSI but was really surprised it stays so low. It's flowing quite a bit of air behind that TVS2300. If you are not monitoring boost I recommend you grab a OBD2 port to wifi adapter and get something like the dash command app for your phone. For $30 you have access to boost and many other parameters.
Make sure to take note of your injector duty cycle when you are at the tuning shop.

Alright guys, at only 7psi and a DA of over 6900ft, truck layed down 501rwhp/568rwtq (uncorrected numbers). I'm impressed as the 568 rwtq hits at just 3500rpm and how much power it picked up through the whole curve. I will pick it up tomorrow morning and let yall know how the "seat of the pants" feels.

What is your SOI look like, good power to be made especially down low.
With these DI trucks when injector duty cycle gets in high 40's you are close to maxing out injectors and pump. (How hptuners interprets that table value). You can monitor boost with hptuners when you are data logging or calibrating, with a roots blower on a mild setup dont see any real need to have gauge as a pd blower boost remains constant just volume of air increases so unless something is wrong or you have the wrong cam the no need imo.
Good numbers i am swapping my 1900 for 2300 soon, but on 5.3. I currently run corn also, will probably run out of pump so have LT pump on standby, hopefully enough cause i dont want to run injectors. Would rather spend cash on whipple 4.5 call resovoir and 2nd hx. If still not enough the alklycontrol kit will go on, plus meth not bad idea on DI truck as will help control carbon deposits.
