Tuning '03 suburban with procharger, 1 bar

[Chunx]

just a few questions.

1. truck has stock injectors, should I get lucas 42lb'ers or run stock and check duty cycle and afr
procharger kit is 7-9 lbs
truck has a rising rate FPR, has no KR, but is running lean
have not checked with wideband but narrowbands are only getting to 850
I have an LC-1 and will begin tuning next week

2. Is this the correct path for tuning?

a. injector flow rate(if not using stock injectors)
b. idle tune (if running cam with unstable idle)
c. autotune VE table
d. power enrichment tuning
e. MAF calibration (if still running maf)

3. when does the vehicle enter PE mode?
I looked at the parameters under mixture but it doesnt tell me when PE is operating.

4. should I upgrade to 2 bar map sensor and custom OS to run 7-9 lbs?
would this be easier to tune with?

5. after I reset LTFT's, how much driving is required to see the results?
are reccomended LTFT's different for a boosted vehicle?

TIA for any help

Not much to add in terms of tuning help.. But COOL project.. Glad I am not the one paying the FUEL BILL on that monster..

ok, I have been told to run 60# mototrn injectors

can anyone tell me when a car enters PE mode
does it depend on throttle position, map, or what?
thanks

Well what do you know I do now have something technical to add here..

FWIW, keep in mind, if you DO run the Mototron (Sp ?) 60# injectors that the Truck Injects are different on the electrical connections than the car(s) ones. Meaning this isnt a direct plug and play operation.. I think speartech sells a conversion part but the trucks run a slightly different electrical connector from what I have seen/read..

racetronix.com sells 60# mototron deka 4 shorty(truck) injectors
thanks for the heads up, that would have cost me some time.
