Hey you SN95 5.0 folks. I know a few of you have moded out your cars, not sure to what extent, but I would like to know what you did, how far you got wihout needing a chip/tuner and if you have any front accy's parts (passenger bracket and Alt) left over? Hoping to find someone local that can help me with project neverending..

I built a 347 for my 94. It's still running on the stock computer, no chip or anything. I'm running a motorsport F-303 cam and the only issue I really have with the driveability is on a hot start up. The idle will jump up and down like crazy and run a little fat, but thats about it. I know a chip would probably do wonders for it, but I still managed a 12.52 @ 108 witha 3680 pound race weight.

well, I have a just the basic bolt-ons right now... CAI, Pulleys, Shifter, 2.5" Exhaust... no chip, no custom burn, just stock ecu... and plan on keeping it that way for a long time... my car runs just fine... and I wouldn't see why on the OBDI system, you'd need to chip it unless some serious engine mods were to happen

same here... i have TB, CAI, pulleys, mid-pipe, catback, etc etc and still running on stock chip.

i don't plan on changing out the chip until the H/C/I upgrade. still TBD.

though eversince i upgraded my fuel pressure regulator i've been having the jumpy idle thing on a hot start as well.

Funny, one of my first engine mods was the FRPP extender. My mods all started by trying to rid myself of that dreadful ping.
I couldn't tell you want all the different stages of my mods were like with the stock computer only.
I will say that add on alone made a huge difference in power and driveability.
I wouldn't totaly put electronic tuning out of the range of possiblity.
Currently I have in the engine:
Cobra Intake, pro-m 75 MAF, 65 TB, 2030 cam, 1.6 stud mounts, '91 forged piston motor, U/D's, 180tstat, FRPP headers/exhaust, oil cooler and the extender.
I had a cold air kit but the sleeve tore. Someone here was kind enough to offer me there old sleeve but I had a new baby at the time and never got back to them.
I modified the stock intake tract to accept the pro-m and it seems to be ok.

I dyno'd 260rwhp and 312 rwtq w/everything in the sig minus, cam, hi-6 ign, t/b, fms extender, c&l 76, and had a huge exhaust leak w/incorrect heat range for my plugs. haven't been to the dyno since I fixed some problems and added all of the parts, but the only problem I seem to have is after a hot start up.

Here you go Larry:

I also still have my ACC. Brackets still on the front. I've also did all the othere basic bolt-ons at one time, so if you have any questions, just give me a shout.

any mod you do your computer is trying to correct or try to figure out why ****s running different so to get the full effect of your bolt ons you need a chip. without a chip some mods can make your car slower

I've got a BBK Cold Air Kit, an E-Cam, full MSD System, off road h-pipe, headers, and a Kenne Bell supercharger. I'm currently putting down 332 to the wheels. I've never taken it to the track, but I'm guessing somewhere in the low 13's, possibly high twelves on a good day.
