Boost levels after ERG Delete, Studs and Gaskets

Hey guys. My rig just had ARP studs, Onyx head gaskets, a new radiator and a Cobb EGR delete kit installed after the factory radiator and head gaskets failed while running the Spartan 310. I'm running the stock-no regen tune for about 500 miles or so before I start turning up the HP. It has been so long since I've run the stock tune that I have forgotten what normal boost levels are. I was driving yesterday and noticed boost levels never exceeded 35psi at full throttle but averaged high 20's to low 30's with normal driving on flat to low grades. In addition, boost seems to bleed off more slowly than before. For example, at full boost (32-35psi) when I get out of the throttle to coasting at idle, it takes about 3 seconds for boost levels to drop to zero. From what I remember, boost levels while running stock were never that high on average and levels dropped much more quickly than that before I had the work done. I realize I'm a bit gun shy after spending about 4K on the repairs and am pretty timid now when it comes to getting into the go pedal, but it doesn't seem right to me. What do you think? Thanks a lot. Dave

It's been almost 3yrs my self since I had no mods done to my truck. But IIRC I never pegged my boost gauge. And the time it takes the needle to settle back down to 0psi doesn't seem too out of line either. I say it's nothing to worry about

Thanks guys.....like I said, it's been a long time since I've run the truck stock. A guy gets a little hyper sensitive to numbers after a 4K repair bill. Thanks again. D
