Hi all,
I've been enjoying my 06 Silverado RCSB over the summer while tuning and making tweaks to what I've done so far. I've had some hiccups along the way, but have gotten this far with the help of some on here as well as scouring the internet for info. Thank you to all who've helped along the way! I've taken this truck to the local dragstrip a few times and can't seem to crack into the 13's which I feel should be very possible with my mods. I've ran plenty of 14.0-14.1@98mph. Cant get my 60' better than a 2.16 with zero tire spin.
Here's my mods:
5.3L L59
BTR Truck Cam
BTR Beehive springs
1 7/8" Long tubes into factory catback w/ magnaflow muffler
4L80e swap with level 4 jakes transmission rebuild
258mm Single disc converter w/ 2600-3000rpm stall speed
4.10 gears w/ truetrac
2/4" lowering setup w/qa1 coil overs and caltracs in rear
17" front/15" rear drag wheel setup
275/60/15(28" MT ET Street drag radials)
I'm hoping some of you veterans can steer me towards my goal of 13's. I think there's a few mph left in tuning. I don't need my hand held, but I feel like I'm missing something! I read about turning down/off burst knock, but I don't see any timing retard anywhere to think it needs adjusted. I've completely disabled torque management which should be present in the more current log and tune file.
It just feels sluggish out of the hole. Maybe it's because its a 4300lb truck with a semi tame converter. I'm hoping that I'm missing something(timing, burst knock, PE, trans tuning etc). My idle/low rpm MAF eq ratio looks like it needs a little work, but thats below the 4000rpm maf enable speed and I'm not positive that there's something modifying that number in the tune. I've played around with power enrichment as well as the timing map. I feel like the timing map is a little questionable as I copy pasted a c5z06 table as my base and made some tweaks to the idle timing as well as wot timing.
FYI: Step21 is the tune ran for the Sept25 file, and Step 14 for Sept 22 1320!
