Hey what would happen if i turned the switch on my switch chip form kenne bell if i wasn't running racing fuel( i know its the racing chip and not the tow/ hall chip)
I can't say for sure without seeing the tune files for your tunes, but if you're asking whether or not you can run lower octane than recommended for the tune, the answer is no. The "race" tune will likely have too much advance dialed into it for pump gas, and you'll go into detonation at WOT.
Ok this is my deal, my truck runs lean when it shifts, under heavy acceleration it drops anywhere from 10 to12 and then when it shifts half the time it goes to 16 and wont come back down and the other times it stays at like 12 then bogs down when it shifts.
I figured it out i knew this thing would run lean but i couldn't figure out why, now i know it happens whenever it sifts down or up. could this be from the cold weather? could it be something with the boost a pump? i do no, is it alright for it to run lean for like 3-5 seconds during shifting? it just doesnt seam consistent.
should i go get this thing dynoed agine and see what the guy says? When it was doing the 16 the fuel pressure was only like 40 and when it was 10 it was 44, that makes me think its the BAP, maybe a bad ground?
Something isn't right here. I can see going lean for a fraction of a second, but no more. Does your application have a BAP and an FMU or just the BAP and larger injectors?
I don't mean to bad mouth the KB guys too much, but I don't think they are really all that careful in their programming. I tried being the team player for a long time, but didn't get things just right until I took matters into my own hands and delivered the truck to a trusted tuner with a 4 wheel dyno.

Do it right, do it once (perhaps twice if you try to run more than 14psi on stock rods, or if you don't read the instructions properly).
It was originally set up for the BAP with FMU, but right now it Has the larger injectors with bap and new switch chip from kenne bell, Fte Herman, for some reason that doesnt surprise me, I just don't have a 1000 to drop on a custom piggy back tune,
The truck has a mass air flow sensor in the stock filter canister. The thing is this worked great all summer after i ditched the FMU, my only complaint was 10.2 at WOT, but then it seemed like this fall and a lot lately i would see my AFR go to 16 in boost, so took it around the block to see what was happening. What i think it could be now is my fuel filter. Do no though but the truck has a 110 thousand on it and for some reason i don't think its been replaced. what do you guys think.
Also these last few times running it at 16, could that have damaged the motor like the rings or valves? there wasn't any destination.
and thanks for all the help

It could well be - I know that 100k+ mile N/A V10 see's pinging for that reason...

hmm... lets just hope not... if you didnt hear detonation, I would be willing to guess (and praying) that it didn't occur.
I just don't have a 1000 to drop on a custom piggy back tune.
Save some money, buy a SCT tuner, and learn your way through it. It makes it a lot easier if you have a dyno to run on, but you can tune on the street. There are at least four excellent tuning resources here FTE Ken, frederic, FTE Fred, and Blurry94.
For the time being, stay out of it when lean and especially if you hear pinging. There is always the possibility of an instrumentation problem (with your A/F gauge) if it is running right otherwise.
I have beat my (second) motor pretty hard at times and haven't broken it yet; however, it does have some non factory parts but does have hypereutectic pistons, which some speak out against.

I second that. I gave up on relying on someone else to tune my vehicles a few years ago, deciding to give it a try myself. It's a steep learning curve, but well worth it. I use the SCT XCal 2 with the PRP and a Innovative WBO2, dyno tuning first, then road tuning.
Ok, it looks like you'll have the support here and in the Computer Chips and Tuners forum: http://www.ford-trucks.com/forums/forum46/. It will be tough, but quite possibly one of the most gratifying experiences you'll ever have.

Ok sounds great but i dont have a clue how to due any of that. My kenne bell chip, i cant reprogram that? Its not the old solid state chip. also if i got now of these SCT chips would i take the kenne bell chip out and then run my own tune? also how much do they run a link would be nice. Do they plug into the diagnostics port or are they hard wired in, so i could try tuning it and if it didnt work out i could still drive it while getting help? I think it would be sweet to try and do that kind of a set up.

Agreed....I've been using SCT software on my 94 Lighting for several years on my supercharged/intercooled 94 Lightning with speed density and now mass air. That software has worked out very well me thus far.
