Slowly learning - critique my dontbsme tune
2002 RCSB Silverado. Pretty much copied the dontbsme combo
Stock unopened 4.8, Sloppy Stage 2 cam, PAC1218s
80E/HD2 with a Jake's 3200 street series converter, 4.10 8.8
Billet 7875, VSR 44mm WG, no BOV, Deka 80s
0411 PCM with 3bar MAP, no MAF
Still working through VE tuning at cruise and part throttle, but my WOT seems okay in the mid 10s.
I am still fighting a stumble on startup (more BRAF?) and some lean spikes during steady state cruise. My other "project" is working on adding some timing to all the non-boost cells as it's kind of a dog until the boost comes on. I think some added timing below 3000 would help the turbo light off sooner too. I've attached a "draft" tune with the stock timing copied over into the cells .5 g/cyl or lower, haven't tried it yet. Other than that it actually drives very nicely.
Feel free to critique. I am a total newbie at this and am open to constructive criticism.
