Im working on a 2007 6.2 GMC denali with a Edelbrock supercharger. I dont think has the correct tune in it for a supercharger. Can some one look at it and maybe can tell me if it is or not.Jaron 2007 SC 6.2 Denali.hpt I think the requested fuel pressure settings are to low.

Timing tables have been modified, PE has been modified. If it is not running correctly, it probably needs the maf and ve tuned. The Normal fuel pressure in your tune is 43.5 psi, and a lot of injectors are rated at that pressure.

Ive logged it while driving and the pressure only runs around that and sometimes dips below into the high 30's.
If it dips that low, you will need a bigger fuel pump. You might check to see if you can get a pump voltage booster as a bandaid if you don't want to swap the pump. You should post up your log and more people will try to help. Hard to answer the question looking at the tune only.

What are the recommended fuel pressures that your pump is suppose to put out?
The FPCM will adjust fuel pressure on the fly. I thought under enough load it suppose to be around that 58psi but can drop down into the 40's when the need for fuel is not there.

If you don't post your tune and logs when you have questions you aren't helping yourself.

Another thing that sucks with that tune is how much fuel is just wastes all the time. It can be at like 30% throttle and over 55kpa and it'll just drop right into power enrichment an blow through fuel like nobodies business. That thing must get like 10mpg doing that all the damn time.
PE shouldn't need enabled until over 100kpa to save fuel with a pedal % of like 40-50% instead of 2%.

go into your desired fuel settings and make them all 58 psi and log it,, ,, do a quick stab and see how much it drops ,,
Ok ill do that tomorrow thks
