Powermax/155's = EGT's?

I've searched. I am thick, but I looked long and hard and couldnt find anything on it, so I'm turning to the forum.
Truck is an 06, CCSB, 6" lift on 37" KM2's, ARP's, 6.4 banjo's, blue spring, 4" d.p to 4" exhaust, built 5R110, billet convertor, 1 piece driveshaft, IDP tunes, IDP 155 sticks, Powermax, Accufab elbow, banks intake.(Thats where my boat money went)
Before the Powermax and injectors I could cruise the interstate at 75-80 with an EGT of 600-625. I'm now seeing the same EGT's at 55-60. Is this normal? Bumped it up to 70 today and saw 800. I thought with more cfm I would see lower EGT's? Wondering if it's leaning out? I will be checking f.p. under load as soon as I can get some dyno time. Gauge is there but I'm wanting to double check.
What has YOUR EGT's done with the Powermax and injectors?
Also, I may be the only one, and I know I am going crazy, but I swear my truck was faster with stock injectors and turbo.
Thanks in advance Ladies and Gentlemen.

Here's the first question I have for you: Did you get your tuning files re-written for the Powermax and 155's?

Yes Sir.
I wouldnt have put the truck on the road until it had a tune. It is a tune written by a very reputable tuner, not sure if I can mention the name on the forum?
Custom files, specific to my truck, will be written as soon as I can get some dyno time.

you added more fuel, its going to run hotter. some people report hotter egts wile cursing with the powermax but lower wile at WOT with stock injectors. This is because its a bigger turbo so its not going to spool and stay spooled as well.

I'm running a Pmax with stock sticks. For tunes I'm running IDP customs rate now.
For EGTs empty at 70 I'm rate around 750-800. While towing they'll cruise around 900-1000. Just thought I'd share.
Power wise it seems to be a little more powerful but with stock sticks it takes alot longer for it to spool up. Kinda miss the getty-up of the stocker.
