your log shows speeds up to 96 mph... how are you doing that if it doesnt run or runs poorly? trying to make it run hard at WOT untuned is burn...

You want to increase it or hit the limiter and keep revving? in both cases you won't be doing your engine a favor specially if the oil pump is stock.

No way this is a factory tune file. Anyone else have a factory tune file with this operating system please? I have a car booked in tomorrow and the...

In theory I would love to know of a good approximate calculation to answer that question. There is definitely a difference, and not just because of...

It does not need the 24X to run a 4x L31 with a distributor or a OBD2 LT1 with the opti-spark distributor used as a glorified cap and rotor. From...

And, if you run as much WOT timing as it will stand just shy of knock, you're playing with fire. WOT timing should be as low as possible to still...

what do you mean that phaser rules i heard fca worked with comp cams to design it : )

correct i tried to mimic it just to get the truck to run however after seeing how poorly it ran i started to adjust other things as well i just...

I'd put the spark tables back to stock for now and work on adjusting VE. You were likely getting KR due to VE not being right. Dial in VE and MAF...

It looks like you copied some random tables from an early 5.3L Flex Fuel file. I see no other reason you would have put 33 lb/hr in every cell in the...

Is there a rule of thumb for how much seat pressure you can typically drop when going from a big(ish) dual spring to a beehive? Comp specs a 1.43"...

A log of it trying to start or barely running is better than no log at all.

Time to go back to the basics. The data for whatever fuel injectors you are using is not correct. Your main IFR is set for a referenced fuel...

Your tune is still set for a 6.0 For an engine with a cam, you have lots to do. Also, if you need to post the tune and the log. We cant see...

IDF and build motor are a problem for IDF. I would delete the idf, and the tune has to be done by a professional PWC tuner; there's more to it than...
