OK this one will likely be a long one so grab a frosty beverage and settle in...
I have an 07 Cadillac CTS V with the following drivetrain mods: TVS 2300 Supercharger, Deka 60 lbs shorty Injectors, LS7 MAF, Omega Thermistor Mod, Heads (GM LSA ported & polished – home job), Cam (218/238 .598”/.615” 12- LSA +2), Kooks 1 7/8” Headers (wrapped), DW 300 Fuel Pump, Kenne Bell Single Pump Boost a Pump, 18 lbs flywheel & MacLeod RXT Dual Disk Clutch, and Tick Master Cylinder
I hired a professional tuner with a very good reputation to tune the vehicle as I new this would be a difficult tune (all mods installed simultaneously and the E67 PCM). The results have been interesting to say the least. The dyno numbers are outstanding (roughly 650 HP at the wheels) but the car only runs well (well at this point is defined as without knock) on the day it is tuned After reviewing the tune, attached, I think I know why.
2013 October 25 - LANES COMPLETED TUNE.hpt
config for v CEF.cfg
5 May 2014.1855.hpl
Again I am just a newb but I expected to see the injector data for the Dekas and the MAF entered along with "scaling" of the tune. Maybe I am just too much of a newb to recognize the changes but I don't think so.
At this point I believe I need to start from scratch and have prepared the following first cut.
base 07 v w Thermister and MAP mod and general stuff (cags, speed limit) inj and ling 100mm maf .hpt
The following is the rationale for the changes included in this tune:

So now to the question. Does anyone see any reason why this isn't a good first cut? Also, in trying to get familiar with the Bluecat tool I imported the stock CTS V LS2 VE data. However, when finished I ended up with the following:

I am guessing I did something wrong because of the large deltas in the data but I have tried this multiple times. Any pointers to get me rolling in the right direction?
For those who might suggest that I take it back to the tuner - He has made two attempts at tuning the vehicle and this is the result. He has had the car for seven weeks during those attempts at tuning (he did two more mods fuel pump and clutch - I later had to redo the clutch - dragging). At this point I cannot see wasting more time with him.
Thanks in advance for any help you can provide.
