Well I have been doing some reasearch over the past few months on the 2 systems. I would have put this in the tuning forum but I thought it would get more replies here. I like the RT because of the data log option but it's over double money here in canada. Try to sway me either way please, Here is what I need to run. Also keep in mind I am going to have a old school chasis dyno to play on to get it to run before I can take it to real tuner 4 hours away.


It has forged pistons, chromoly rings, hardened bearings, edelbrock rolling thunder cam with .520 lift inake and exhaust , edelbrock performer 170cc 194 heads that I ported, edelbrock performer upper and lower intake also ported, ported intake elbow, 1.7 rr's, 75mm throttle body, 42 lbs injectors, adjustable fuel pressure regulator, poly motor mounts, canton 7 qrt kick out pan, windage tray and crank scraper, high volume oil pump with hardened drive, msd pro billit distributor, msd 6al with rev limiter, ford racing wires, Vortech S trim super charger with 3.33 pulley, anderson ford motor sports power pipe, 80mm blow through maf meter, tfi balancer, vortech t-rex 255 lph in line fuel pump, and bbk 255 lph intank pump.

Also the maf was originally for a fox and it cald for the 42's. I am really unsure how to set that up but that's why I have you guys.

Thanks

Well that depends on if you want to tune it yourself or have it professionally tuned. To tune the SCT yourself you need the Pro Racers Package, which runs in the $800(US) range w/chip, and doesn't have data logging. You could find a used AEM for around $800-1000, which is what I did.

What I originally did was buy a mail order tune on a SCT chip, than had it tuned later. That was great for a while, but I didn't like the fact that I couldn't adjust the tune myself so I switched to the AEM. I thought about going with the Tweecer instead, but I couldn't find a good deal on one at the time, and I thought the used AEM was worth the extra money over a new Tweecer.

like Mike said, it mostly comes down to whether you want to tune it yourself on the fly or a once and done thing. i've had both and the chip was nice but if you add anything to the system your back at the dyno for a reburn, where if you tune it yourself you can just tweak it.

both systems are good but you'll have a serious learning curve for tweecer

Ya that too much for the sct, i plan on changing things here and there to get maximum potential from the car. I have some very knowledgeable people that will help me tune, and I like the idea of doing it myself. I know it will take a lot of work but that's alright I don't DD the car anyways.

With that said and I know it should propbably be put in the tuning section but hey what the hell.

I have a couple different maf sensors. the one that cam with the vortech kit is calb for the 30's and I have one that came with my fox twin turbo kit that is calb for the 42's I am using. With the tweecer does it matter what maf I use. I assume (and once again very grren and just leanering the self tuning with the tweecer) that I can tell the tweecer what maf I am using and have no issues. They are both pro m but very differnt from each other in many ways. Especially how they would hook up to the power pipe. The one for the 30's fits the best but apparently the one for the 42's is a blow through and a slightly larger diameter.

What do you suggest?

All help comes with great thanks

Try the Moates Quarterhorse thats what I have, works like a charm and cheaper, 255 for chip 130 for software, 180-200 for a wideband= $580 or so.

the one cal'd for the 30s is a draw through maf while the 42 cal'd one is a blow through. i was always under the impression that the blow through is for an inline system like a turbo because the tube is presurized where as a draw through is best for a n/a or pre supercharger setup. someone correct me if i'm wrong.
