No worries, just remember all of this could've been avoided had you just answered an email, pm, or phone call. The worst thing is that we'd be on LS1tech at the same time, I'd click your name and it showed "activity" reading private message from allngn_c5. Well if you took the time to read it, then why didn't you respond ?? I am at a loss. Read it and ignore it, why? Oh well, its all done now. A couple more grand out of my pocket (courtesy of the members that bought my parts THANKS) and she'll be perfect.

Keep in mind that I am not saying anything negative about the quality of the build. Just saying that I as the customer was not listened too about what I wanted done. Vengeance assures me that they will do what I ask, and price for the work is very fair. Again sorry it had to go down like this. Maybe if I was a Texas local instead of a Michigan resident you'd have been a little more willing to listen because I'd be able to drop in anytime and talk to you face to face vs hoping for a response via email or pm etc.

Please lock this thread Pat G or whoever.

I'm curious as to how much more power you make with the TFS 215s over the AFRs.

Interesting I have never heard of a stock pump able to supply enough fuel for 520 rwhp? In what year did they have these high output pumps? I was ALWAYS under the impression a stock fuel pump could only supply up to around 480 rwhp give or take with the right injector.

This is what I do for a living. Most stock pumps max out around 550-575 rwhp. Turbo cars routinely make 550+ on stock pumps at much richer mixture levels. I maxed mine out at 525 through an auto. Who ever is telling you stock pumps max out around 480, you need to omit their response from your search results

Louis - Just for clarification you're referring to the C5 fuel pump and not the F-body; correct?
