For those of you who live in the Houston area, Did shops like M.T.I. (Motorsport Technologies Inc) do custom tuning back in 1997-2000 when they installed superchargers, blowers, cams, heads, etc? Or did they just let it roll out the shop running factory tunes?

Just wondering, they used to do a lot of fox body Mustang boltons etc back in THE day when 5.0s ruled the streets and I wonder how did they tune those cars? And then when the LS1 came out they got all into that and did all kinds of mods on LS1 cars, and I am left wondering now, did they tune those cars or just let em roll out with the factory tunes? Did they LS1 Edit? Because other things like HPTuners wasn't even availible back then right?

Anyone know for sure? Was LS1 Edit even around back then? Did they have some other kind of "machine" that let them tune the cars? Like something a Dealer Service Department might have?

 

I'd like to know this too.
I'm from houston. I graduated HS in '96. Back then any idiot that wanted a fast car just bought a 5.0 mustang and went to town w/ bolt ons. A lot of kids at my HS had mustangs w/ work from MTI. (I grew to loathe mustangs. ) I even thought they used the "Motorsport" name because they did so many mustangs. I know back then before the EEprom alot of guys were running the hypertech and jet chips. I think they would even burn custom chips (not sure).

I'm not sure when LS1 edit came on the scene. I found out about it right before I found out about HPTuners and EFILive. There was an LT1 edit before LS1 Edit.

Surely someone here knows if they tuned those cars or not. 2 people I know had mustangs of the era and did the bolt ons thing like so many did back then with the 5.0s and they had no custom tuning. I guess they just slapped a cam and heads on the car and ran it with the stock tune. I guess back then 94-98 (being a carb/vacuum advance kinda guy back then) I just assumed with the MAF systems they sensed more air and therefore added more fuel, but what about the spark curves? Knock retard etc.. how did they deal with those things back then.

I had several GM TBI (pre vortec) trucks, 2 4.3v6 5speed and 1 5.7v8auto truck all RCSB and I only did mods to one of them, 92 4.3V6 5 speed had underdrive pulleys, no cat, flowmaster, and hypertech chip. I don't remember which hypertech chip... I never really thought of making hot rods out of those trucks, I was playing around with old Carbed stuff for speed back then.

 

I forget when lt1edit and ls1 edit were introduced, but a few guys can do it the old school way. There was some software avaliable but not to the general public.

I know of a few guys in the southeast that did hex editing in the 80's. They were the group that started SCT and a few other brands. Tuning can be done with hex editing but it takes forever and the addresses have to be accurate. The software takes off hours even days b/c you click or drag instead of manually going in and changing numbers one by one.
