Got it running this weekend. I was not able to set the timing though. Tried to use Car Gauge Pro but it would not read my ECM. Perhaps because it was tuned? I guess I'll try the local chevy delaer. Not throwing codes but I dont think its right. Get a misfire, well hic up while under light load at low RPM. Just kinda acts like its not set right.
Speaking of tune, I opted to tune the black box. The tune is for crap... Runs VERY rich. Lots of surge which I expected because of the duration but its just, well so "base tune". Maybe I should go with the 411 PCM?
I dont have a shop around here that will work on tunes (for this truck). Does the 411 support email re-flash? Start with a base tune, data log with a hand held and email a file etc...?
BUT - all in all with 150 miles on it I can tell you this has a TON of torque. Hopefully I'll get the tune/timing worked out by break in...
