Gains from LT headers inside Well last I dyno'ed at 306rwhp/320tq, added Jet-Hot Lt's, removed AIR, EGR, and used the predator for partial tuning (still rich as below), and new dyno at 325hp/335tq @ a N2O friendly, but not used 12.5:1 AFR. Have TM turned disabled, COT off, as well the rar O2's and other codes associated with header install. Not sure about convertor locked unlocked, we pulled it in strapped it down and dyno'ed, I just wanted the WB readings.
Guess it would be better with a leaner fuel, but since I am wanting to spray (where's my NXL kit???)i can live with that.
Track sucks too much to get a good read, but picked up +2mph, and dropped around 2/10ths. All in all happy for the 5hrs on the garage floor it took me!

Re: Gains from LT headers inside Prior to my Hookers, I dynoed 309rwhp/322rwtq. After headers, I dynoed 332rwhp/344rwtq. I dynoed tuned it with LS1 Edit and a 12.7 AFR. Good luck tuning with your Predator. After helping a friend try to dyno tune his, we gave up and went with Edit. We couldn't get more than 23 degrees of WOT timing with it, and couldn't lean it out enough either.
Nice numbers!

Re: Gains from LT headers inside URPREY- I have the predator and I get 31* WOT, and as of last tuning read on WB I was at 12.5afr. Working with James I am reducing the fuel 13% and mod'ing the low octane tables. So far I am happy with it. Did you go off the Generic performance tune, or was this after sending and receiving his custom tune? Not flaming but there are a lot of people I know using the Pred. and they are assumingn the perf. tune that is delivered with it is THE TUNE, when it is merely a base to go off from. I used it, monitored live data and then emailed the results to James, who inturn had a file, actually two, and emailed me back. now we are just tweaking the fuel.
Smoke Ford-what problems other than tuning the AFR? I installed the JH LT's in about 5hours laying in my garage, with hand tools. No problems, just read the info tips and asked a few "?" before i started for the tips to make it quiker, and they worked!! End State-Yes I think they aremore than worth it, looks nice, under-hood temps are down, and exhaust flow improved, sounds good too!
