First time getting into tuning and working on getting my 5.3 swap going. Im hoping for some constructive criticism and help getting in the right direction.
Here's what I've got going;
02 LM7 - 5.3
700R4
BTR stage 2 Truck Cam (Low Lift)
Speed Engineering Shorty Headers
2.5" dual exhaust, Wide band has been ordered and on the way.
8.1 Injectors (Delphi 25343789) Flow rate: 270cc/min (25.5lbs/hr) - 43.5 PSI (Reg set of 55PSI currently)
80mm Throttle Body (Got it for Looks)
Front O2's only.
Ive had to adjust the Idle to get it to run, Also played around with fuel and Spark tables to get it running a bit better. Also I took the VE table to +/- 10-15% by doing some experimenting and it seems like it likes about 5% less. however I did just change my plugs which showed really lean.
Currently It will run and Drive but doesn't like to start right up, I have to pedal it a bit to get it started and get the RPM's to stabilize. On the road it will accelerate ok to start but falls right on its face at any throttle over 33ish %.
I tried uploading my Tune and Log but its not working. Ill update once it works.
