Sweet Looking Truck ❤️. Curious if any tuning issues with that LSXRT? Enjoy!!!

interesting that you ask. YES, an idle issue, wide open and part throttle are perfect but from time to time when coming to a stop the truck will drop idle and then hunt for the desired RPM and sometimes completely stall.
do you have the same issue ?

I did back like in 2009-10. I would have trouble starting it. Had to crank it like 5-6 times before I could get it started, then had to rev it to keep it on, then stall at about every stop stop sign or light. Had to try to yield only on stop signs and try to catch green lights. After about 6 mm months, just got fed up, removed and sold. It's been years since, and since I keep seeing them around, get curious if Fast ever fixed or their issues or same is why I asked. I guess not. And yes wide open and part open throttle response was awesome. AGAIN, SWEET LOOKING TRUCK. LOVE IT.

FWIW - had same issues with my LSXRT on my 91RS. Got rid of the LSXRT and all of those issues were solved.

This sucks...... I had a perfectly running holley sniper 102mm that looked so perfect on the truck but I started chasing power and bought the FAST, I gained 3 hp at peak but did gain 30+ in the midrange, in hind sight I should have left it alone with the sniper. Might be time for another intake swap.
