Barts daddy go have seat or play with some more pipes lol j/k man keep doing what you are doing ......No harm meant but seriously many people have it working right with a car that has been tuned.... again my point of this thread is that the lex afm and stock 440's need to be tuned!!! My a/f are...

isnms but i am not asking for help i am just stating my results I understand lol but man there was a thread a while back where the guy was stating that he pulled the efi fuse and the ECU relearned its self back to a good tune ....... I said i was going to make a thread about it and post my...

I was asking about your current mods and fuel cut ...... your response was that you started to lean out at 18psi or so i am going to dig it up. I am sure I saved that convo

Quin ..... we had some PM's a while back about it but i was trying not to be too specific :) but are you guys running on the stock settings like fuel pressure and stock ECU fuel maps w/o any piggy back scaling?

Nick the point i was making was that i dont see how other who have posted that their were able to run the lex afm without any changes with the tune.... I agree with the other members who say dont run the lex afm without a good tune. Was the point I was getting at.

I find it funny that you find me funny since I said I am on the stock fuel system and you are posting that you have AFPR and a Walbro apples and oranges. You are pulling to much fuel at 22%. Read below.... That walbro move so much fuel than the stock unit. What do you have your fuel pressure...

Are u asking me or him? I am on the stock fuel pump, FPR, and injectors. I am using one of the AEM widebands and SAFC-II

I cant see a bad ground being the issue there with you. Cap off the nipple that goes to the brake booster and see if that helps ..... it will just make braking a bit harder until you put it back.

umm i hit fuel cut around 16psi but that probably b/c i added so much fuel if I had scaled back some fuel and added fuel using an AFPR it might be able to go 20+ yea it felt alot faster but i am so used to more power that it wasnt all that .... 300rwhp isnt much after you you get hooked on...

Sounds like a boost leak.... fuel cut comes from the AFM singal and since the AFM is first in the system the IC and pipes would not effect fuel cut unless it is leaking boost pressure. Boost leaks cause the AFM to read a certain amount of air coming in, but that air that was accounted for is...

Well guys i spent today playing around with the Lex AFM and the stock fuel system. I am not sure how some of you guys were able to use the Lex AFM on the stock fuel system and stock settings. I think it would have been find with AFPR even without a pump. I pulled the fuse EFI fuse and also the...

You want the shortest distance from the throttle body for the BOV and the shortest distance for the vacuum line from the vacuum source .... period.

my friend just dynoed yesterday and put down 357rwhp and 370tq @ 10psi on a 57trim on the stock fuel system .... well with a APFR sooo thats makes it 2/3 stock leaving the stock 440s and pump. he is tuned between 11.9-12.4 @ WOT

Yea i like BOV .... You have to pick which parts you cheap out on. Metal IC pipes, BOV and IC i can understand. But I would not cheap out on on fuel related stuff and pistons.

yea i believe so

http://www.racetronix.com/17113841FM.html these are pretty close to 550's cant beat that price ......

Compressor surge is bad thing and can shorten the lifespan of your turbo. The stock BPV doesn't make a sound unless it is vented to the atmosphere. Its good for about 10psi but here is the problem .... How old is your stock BPV? Old enough to be replaced but its not worth replacing it with...

LOL are you serious? Did you actually read there "website" ..... which one sounds like it has more/better features? The Maft Pro of course! OR you can simple go the 550 injectors and Lex afm route and when you feel like you want more power the get a SAFC. The lex afm and 550's will support...

Ummm you can hear it very well in you video right at the 12secs, 15secs, 45secs, 1:15mins, 1:22mins its the the fluttering sound you get when you left off the gas during WOT to shift gears. Thats if you are still on the stock BPV which to me sounds like you are. But i could be wrong and maybe...
