That's a funny comment... when did you buy a chip from me craz azn? Did I miss something because it sound's like you tested my work?

FYI.. Both of our chips are great and almost identical in power increases for the M42 motor

Would you buy no name brand coke or Coke Cola? Same thing Plus the real deal is always just a bit better haha.

But seriously though, Mark's been in the business for a long, long time. I'm willing to guess you haven't? It's always good to buy from a reputable source than a 'one hit wonder' brand. I mean, if you aren't, please educate me on who you are, your achievements in regards to tuning, etc.

Even if you say you have almost the same gains, have you compared your dyno plots with MarkD's software? Peak gains aren't that interesting to me. Useable gains are. I have tested his chip once before in a E30 318iS, and it sure made a hell of a difference in the butt-dyno for torque.

Non-sponsors aren't allowed to post their merchandise on the forums BTW, just an FYI.

Have you tried out bmwconnects chip in a car? I'm interested in what you found, I'm in the market for a chip, as it were. Did you have it dyno'd independantly of what he just posted?

I've found Spritz Up is just as good as 7Up, for a better price.

BACK TO THE ORIGINAL QUESTION:

Yes, a chip is good. Injectors is a nice mod as well, the stock ones quickly fail to deliver enough fuel as you get into the higher RPMs. Cleaning your stock ones, if it has never been done, will do a lot to get power out of them again. A kit off eBay will do fine, just clean them off, replace the filters and make sure they're still squirtin'.

In terms of replacing them:

Mustang GT 89-98 19lb-hr
Mustang Cobra 89-93 24lb-hr
Mustang Cobra Supercharged 39lb-hr
Almost all ford 4.6 and 5.0 motors 19lb-hr
Ford SVO mustang, turbocoupe, xrti 35lb-hr
Ford Lightning 99-04 42lb-hr

Stock e30 injectors 13lb-hr

Be aware, that upgrading beyond 22lb-hr on a non-turbo car is not going to really be a wise mod. I'd say go for the 19 lbs and call it a day in that arena.

For the intake, which is another choking point for the engine, a popular mod is to swap the M30 AFM into our M20 engines. Dynos show it giving (in combination with 19lb injectors) about 6 HP and 5 lb/ft of torque, and quite evenly across the RPM curve, so you're not loosing in one area to gain in another.

Here's a great DIY for the swap. http://www.davelength.net/car/bigsix.html

Once the air intake and injectors have been upgraded, a chip would be a great idea, to fully realize the gains possible for your now less restrictive engine.

MY 2 CENTS:

Before you start hitting up the engine, I'd deal in the suspension area first. If you're looking for a fun, quick commuter (like me) then suspension is going to be the one you notice fastest. Especially as we are heading into winter and even 50 HP Geo Metros are getting sideways.

If I'm totally wrong on all counts, someone feel free to correct me.

REMEMBER: Be safe and have fun is rule number 1.

First off, the m42 already has 19lb injectors. Don't touch them

personal experience, from my 91 318is

Mark D chip - major improvement!!!
4.27lsd outa a 318 vert - stock diff is 4.10, just enough of a gear bump to get going alot better without sacraficing high rpm on the highway

toss in some suspension lowering and a ssk and it's super fun

you can also adjust the cams in the m42, forget the actual adjustment but it's easy to find online.

You can also go to a single mass flywheel, but it's susposed to be pretty hairy in the wet

I also have a manual steering rack if you want to gain a few ponies, also if you can live without ac, loose it. Electric fan and loose the clutch fan too

tires tires tires, better tires and light rims!!!!

There is no way that's a chart for a stock m42 and a chipped m42. 160 stock??? WTF

richie_s999 that dyno plot was a measurement taken at the crank hp
red line represents the first pull
blue line represents final adjustments for best/safe power on 91octane

I'm sorry, but I've NEVER seen a dyno and AFR plot like you're posting for your product. They're almost both identical in shape and form to each other. Not to mention torque is being measured in Nm? Who's product are you using? And what dyno machine was used and where?

I'm going to call BS, sorry.

And why would you leave the AFR like that anyway.
