Do they still sell the old parts off your car to get the money to buy the go-fast parts for someone else's car?[/quote
I don't know what your personal experiences with HPE, either their Texas facility or their Lake Forest, CA, facility, have been, but here's mine:
God Bless the Hennessey (HPE) Lake Forest facility & its personnel.
About 3 or 4 weeks ago my ’09 CTS-V with the HPE 700 package developed a noticeable high speed miss. It would be fine in the AM’s when just started, but when warmed up it had a miss in it. I thought that this was due to a tank of bad gas as I had just filled the tank the morning before. After adding a bottle of Sta-bil & 2 bottles of Heet, it would run fine for about 5 minutes, & then go back to its less than desirable attitude.
William Rollins suggested that I bring the car in to their shop. I took it in & they gave me a ride home.
A day or 2 later William called me with great news. The spark plugs previously installed when the meth & headers were installed was a tad too cold with the meth and at boost the spark was being blown out. They also did a compression test, leak down test, & a base line dyno at my request to verify that the car was putting out what it was before (658 RWHP) & they are delivering it to me today. Even though I told them that I would foot the bill for everything they told me that I could pay for the spark plugs ($40) if my conscience was bothering me but everything else they covered under warranty.
So bottom line HPE gave me a ride home, Changed plugs, did a dyno, leak down, & compression check, & delivered the car to me at my residence & would not take any money & / or compensation for everything done. It is just impossible to match &/or beat their customer support & service. They have stood by me through & thin & you just can’t find this type integrity, customer support & loyalty anymore.
