Yes, my comment was specific to modification of the PRV.. The quote below was "improvements to the PRV". Maybe I should have been more clear and said Modifications to the PRV. Sorry! As a result of my time looking to modify the PRV, I am now working on a conversion... If that tells you anything! -----Original Message----- From: Jim Strickland [mailto:ihaveanaccount@xxxx] Sent: Thursday, November 01, 2001 2:56 PM To: dmcnews@xxxxxxxxxxxxxxx Subject: Re: [DML] Re: fuel injector / HP Gains I think your numbers are only applicable if you're trying to update the PRV. Where's Darryl Tinnerstet? He has over 300 HP, and I'm sure he spent a lot less than $13K. And the guy with the 4.3L Vortec I'm sure is under $80/Hp. This brings us back to the price/performance index. Time to check the archives... 1537 On Thu, 1 Nov 2001 10:55:25 -0500 "Marc A.
