Jeff Doesn't have a 454 starter tune, talked to him yesterday
I appreciate it. It will sort of run, but won't idle. not sure if its the cam timing or not
i'm dealing with a misfire on mine. Not sure i have a solid base tune though.
also curious. looking for some bigger stick myself for my whipple blown 454
what gauges are you running? The Dakota digital package comes with an electronic vss you could tie into
Anyone have a good base tune for an l29 with an 0411?
I'd like to keep maf functionality. I may need a better base tune
No, just a base tune. I'm still running the Whippletronics until I get my larger injectors.
I did my 411 swap today.
97 k2500 7.4 with Whipple.
It ran great before the swap. Now it runs like ass, I have to hold the gas to keep it running. Not throwing a CEL but I pulled codes p0103...
thanks for the info. hope I don't run into this
for some reason, it won't let me send one. My email is spastikmonkey@gmail.com
i'm in the same boat
Does anyone have a tune file for a 454/4l80e combo on an 0411 pcm? I'm doing the 0411 swap to my 97 k2500 suburban, but I can't find a 454 tune file.
