Default Tuning a Foixbody with a KenneBelle

Just installed a KenneBell on a 331 stroker motor. Car really pulls hard above 2000 RPM, but is really rough below that range. Really bad on fuel usage. I think a custom tune is in order. Coach me on what devices are available. We have a dyno tune shop locally. Coach me a little.

Pretty sure to use the stock computer you'd need a chip and someone that can (still will) custom tune it on a dyno, don't waste time with mail in. Other options are a Mega/Micro Squirt (I've got a megasquirt) and tune yourself or hire out, or a Holley which are supposed to be awesome but much more expensive.

KB will do a custom chip by mail. Just send them your mods and it will be close and safe.

I have a Moates Quarterhorse, a Burn1 chip burner, and a chip I will sell for $200.

The Holley EFI is the shit. I have it on two cars. It will do anything you want it to do and then more. It ain't cheap though.

Sorry, but I think this is really bad advice. There’s no chance I’d do a canned tune especially on a Forced induction setup. A tune needs to be adjusted while monitored.

Your options are:
-new modern ecu $$$, it will still have to be tuned
-dyno tune with a SCT chip from a local shop, this can go bad - most shops won’t want to mess with it and if they can’t get it right they’ll claim you have a mechanical problem and send you out the door to get it off their dyno.
-Moates quarter horse and do it yourself. Steep learning curve.
-Moates quarter horse and pay someone to tune it remotely. There’s a few out there and they are weirdos.

Your best bet if you have the $$ is an aftermarket ecu and someone locally to help tune it.

Similar to the megasquirt that I have, good stuff, and Doug (Bluecouperedvert on here) can tune them pretty well if you need it.

Thanks for the input. I think a new system instead of the add on chip is the better way to go. I already have a gazillion in the car, but isn't it always like that with toys ?

The guys I know that have the pro-m swear by it and the owner of pro-m from what I understand will practically tune it for you.

Foixbody, I have nothing intelligent to add, but every time I read the title I think of a woman up north saying “foixbody”

A stand-alone aftermarket engine management system is really the way to go but KenneBelle's off-the-shelf chiptunes are really close to perfect because of their many years of experience and broad knowledge base.

If you decide to go with a stand-alone system the learning curve is pretty steep. Getting the fuel right is pretty easy but getting the timing right is difficult to do without a lot of previous experience. Contrary to popular belief timing is where your power comes from; your fuel mixture assuming that you're relatively close to where you need to be doesn't alter the power that you're putting down all that much but it does have an effect on durability
