Chevy 8.1 Whipple
I bought a Silverado with the 8.1 and a Whipple supercharger on it. The Whipple electronics were ditched and the ecm is now controlling it all. It has marine 40lb/hr injectors in it as well as a higher volume fuel pump. Thengine was dyno tuned in Denver and I have brought the pickup down to Nebraska, lower elevation. It has started a slight misfire under load in overdrive. We hooked a snap-on scanner to it and were looking at the long term fuel trims coming in at a -9. I'm on the edge of buying a predator or something like it from diablosport since that's all I run in my diesel. Is it possible to build a tune I can work off of with a predator or intune? That -9 tells me if I'm not mistaken that its on the rich side and I'd like to do some work to it. Any help appreciated

misfire is a physical/mechanical issue, tune won't fix a misfire.. check the plugs, make sure no cracked ceramics.. check plug wires, make sure all are completely snapped on the plugs and coils.. check the coils make sure they're all good.. clean the MAF sensor...

I also have a 8.1 l with a whipple supercharger it has all whipple electronics still hooked up I'm getting a p0103 at times can my trinity tune for this condition
Re: Chevy 8.1 Whipple
that's a MAF sensor trouble code.. bad maf sensor, or some airflow is really off somewhere.. no can't adjust anything for that with the trinity.. you need to take it to a shop and get a custom tune done..
