Greetings guys
Been using this forum 4ever but I decided to join
tons of info and it really helped me out so I am hoping someone might have some ideas on solving a problem I currently have.
My dad gave me a 1999 yukon that had a blown bottom end and was sitting for a couple of years
I took it and put in a rebuilt engine and tranny
Engine
4 bolt main not 2 bolt
forged Steel crank
Bored out
Everything else is stock
Complete exhaust system front to back including headers
Tranny
Rebuilt ..but tranfer case was old but cleaned
So I started to have this problem with no low end power RPM 1000-3000
Brand new and I can not even smoke the tires and going up hill she has zero power
I had a check engine light telling me she is running lean but I fixed that with the MPFI conversion no check engine light but still no power
recently i did
AEM intake
change to MPFI
change the MAF sensor
check fuel pressure 54 running 61 w key on
brand new cap rotor and wires
After doing all of this she still isnt running her best.
I put her on the dyno and the guy told me 197hp including all the mods I just talked about
here is the video

Anyways
Is there anything I forgot to check or change ?
Am I just crazy and no one can burn out there 99 yukon ??
trying to understand what to do next
Thanks
