The early 325i came with the 153, the later ones came with the 173. I don't recommend the Dinan chip for our E30s.
The one made by Jim Conforti(aka Shark) (Bonneville Motorwerks), and sold by TMS(Turner Motorsport) or Josh MacMurray(Eurosport), make more HP and Torque, and have a higher Rev limit, 6900rpm. Price is $249 for a new one.

Turner's site:

Eurosport

You can find a used one on ebay, only buy a Conforti or TMS chip here, not the Hong Kong knock-offs, they run around $100 for a used one.

I got dynos run with the Conforti & stock chips a month ago. To my surprise, the stock chip produced +2hp and +2 ft/lbs over the Conforti chip over the entire rpm range. Well, until the stock chip hit the rev limit, of course. My engine is stock, with a cone air filter, no cats, and straight-through muffler. Huh!

that really surprises me.
ive got the dinan chip and (im not racing) im pretty happy..but again. i have nothing to compare it to, b/c i thought i felt a huge difference it maybe all psycological...

its sort of a pain to open the ecu and ive never even had my car dynod, is it worth it?>
what should i expect to pay?

I was surprised, too, as I'd thought I felt at least a small improvement with the chip. The dyno shouldn't lie, though. I paid $90 for 4 runs, but I've heard of groups getting runs done for under $50 per car.

This weekend at Willow Springs I tried both the stock chip & the Conforti chip. I was able to run over 1/2 a second faster with the Conforti chip, but I would chalk that up primarily to the higher rev limit which gave me another ~10 mph or so coming into, through, and ouf of turn 5, which leads onto a very long straight (4th is too high around 5, 3rd is just about right with the 7k cutout...if I could only safely rev it up to 7200 life would be perfect Laughing ).

i have to ask..


were you using high grade petroleum? like 91 or 93?

and if yes.
then i suppose my chip made me"feel" like it was performing better.

as when people drink non-alcaholic beer, and get drunk anyways Surprised
