O.K. I am very pleased with my 2 pulls the 2nd pull was more than the 1st which is normal for my truck it just does not like running cold.So Here is the numbers I'll post the graph and video of the pulls which were back to back with no cool down time. My question is watch the exhaust and at the top of the 1st pull if starts to puff black smoke I wonder if this is spark blowout the engine never seemed to miss at all. Of and with a tail pipe sniffer I was at 12.5 to 12.7

Not bad for a truck!!!!
Here is the video:

Trucks a little lean. A/F should be around the 11.7 11.8 area.

 

Thats true but this is after the converters with the tialpipe sniffer wouldn't that show it leaner.

That seems like little fuel puffs. Could be a high Rpm blow out issue. You won't allways feel it so that could be an issue.

 

The difference is minimal, barely .1-.2 change. It's too lean as is.

 

Too lean I guess I need to get James to richen it up then. I'm running my 15deg winter tune because I was getting detonation from the 17deg program James from RWTD gave me.

the sooner the better

 

I agree l-menace do you think I'll be O.K. going to the track running 110oct that should richen it up and give me some safety until James gets his site up.And also would my figures have been higher with more fuel? I check my Preditor I datalogged the 2 runs and the O2 reading held steady at .85 which is rich but not rich enough for my liking. Temp was 65deg outside IAT1 on the 2nd pull was 94deg and IAT2 went to 138deg. I thought I had my MAF set up to make sure I was not pegging it but I had it set for aif flow instead of Volts do you guy think I would peg out the MAF with a 6#er?

You guys think I should buy a MAFExtender or MAFia just to be safe. I checked my datalog on my Preditor and I was a .85 on the O2 during the run don't know where the MAF was at because I check the air flow MAF section by mistake instead of the volts.

Will I be safe running this tune with 110oct race gas at the track Friday doesn't look like I'll be able to get James to return my e-mails I can't get him to answer the phone or anything. Really like to go to the track Friday been trying to go all year.
