Keep in mind my truck swifts at 5300 RPM's on WOT. The time the truck shifts it's at 12.6 on A/F. What are your thoughts?

 

your A/F curve is odd.

Starts off Lean, then goes Rich, then on the High Rpm's it goes Lean.. A little TOO lean for me.

Your boost is a little flat also, mine starts off and slowly rises up as the RPM's increase. It jumps to 12, then climbs up to 15-16 (depending on temperature 17). It nevers stays constant.

 

what pumps, injectors do you have?

255 pumps. Still have stock injectors. Plan on having 60's installed when I get the Whipple installed next month.

 

Yea George...thought your A/F was a little weird myself. But I don't care what that sheet says...your truck is pretty mean. And is going to be worse when you get the whipple on

 

You're beyond the level of stock injectors. It is definitely leaning out at the top and I'd keep my foot out of it until you get the bigger injectors. Ask me how I know.

The boost wasn't hooked up right. THe boost isn't at 10 before he hammers down. Got me wondering how he hooked it up. It is leaning out too much at the end. Even though you have a built motor det. is going to hurt you still. Get it around 12.0. Injectors may help but I would suggest another tune when you do change them out.( have your tuner make the changes to richen it up at the begining and end.

 

Great numbers George...

as stated.. until you get new injectors I would hold out on any WOT runs... Side note... on NLOC I saw someone who wanted to swap his 50#'s for someones stock... might check that out George???

What mods??? for these numbers???

 

Plan on getting 60lb injectors and tune when I get the Whipple installed.
