I picked up on this thread a little late, looks pretty interesting. If I read correctly, seems there is a comparison of FP vs stock computor..... I am definitely a FP kinda guy, for many reasons I have read here, but, if I read correctly, L\U and AC can't be used with an FP? Not sure why, since we've been doing it on cars here for some time now. The AC is just a matter of hooking up one ground wire and the L\U is simply installing a BM L\U kit. So that isn't a problem or deterent for using an FP. As for a B2B unit vs Sequential, I've tuned mid 8 second cars with a B2b with no ill effects. I've run a B2b the last 2 years running 9.70's with no problem and good street driving manners. WOT doesn't much matter either way since fuel is pretty much just dumped at that point. Tuneability with a FP isn't even a comparison between the 2 as minor adjustments can be done simply and at any time with a FP. I've watched many guys with "stock computors" run a number 1 day, 1 time and blow up the next or not even be able to run close to their previous best. When my car runs bad, it runs better than most chip cars run at their best. Every chip car, from 11.50 and faster we've installed a FP on has gained at least 2\10ths out of the box and better street driving manners. I'm not trying to sell anyone here, just sharing my own experiences on a daily basis. One more thing, I've never had a customer that we installed a FP or FAST on ask to have a stock computor put back in. OK, so I lied.... one more thing, how much does it cost for a modified computor, trans plus, extender chip, scan tool and whatever else is necessary to go that way?
