HPA = Top Notch in Customer Service!
HPA = Top Notch in Customer Service! Just wanted to let everybody know , if you plan on going to HPA for any install you are not going to be disappointed! I brought my car to him for a PP 5.3 stage2 Head install. When he was finished installing my heads we put it on the dyno(25 min.from the shop) and it dynoed lower than just my cam only car (TR220.561). We knew somthing was not right with this dyno. A couple of days later we brought it to an dyno he had been using before but was not avalible the time when he first had my car done (10 min. from the shop). The numbers this time were in par for what i had done 385rwhp,385rwtq! He felt this to was on the low side as so did I.He took the car back to his shop and did a leak down test, compression test, and every other test imaginable!Everything came up good , car only has 6000 miles on it.He took the heads off and installed some AS 5.3 stage2 heads that he ordered for me.Before we were ready to go back to the dyno he noticed that my Alt. was not charging properly.He would not take the car in that condition to the dyno until he found the problem. Him and his team found it to be a bad Alt. wire plug. We went back to his normal place to dyno(10min. from the shop).It put down the same #'s as the PP heads 
. John did a tune on my car and found 13rwhp and 9rwtq more! 
Now i'm at 398RWHP, 394RWTQ not bad for a small cam that i have.
John never charged me a dime more for all of his time and money to make sure my car was right BEFORE it left his shop. You are the man John
Now that is some customer service!
Thank You
