My builder installed the 9510XS on my recent build. It has been flawless so far. It was easy to clock. Long term, I can’t say yet. I do know it only comes with a 1 year warranty from date of purchase. I guess I deferred to my builder on this. He told me it’s all he uses and said they are very reliable. Builders name is Randy Repp. Owns Pontiac Speed Shop in Brownsburg, just outside of Indianapolis. Good luck
