anybody dynoed stock 325? What were the results? My fried dynoed 325 coupe and found only 180 horses. Engine is really good, consumes no oil, no bad sounds, runs perfectly. After chip it showed 187HP. But with stock chip, without filter and cold air intake it pushed 192hp. What should he check in the engine?

Did he have a fan blowing in front of the car? Without that, the is NO air movement over the CAI, which will lower the dyno graph because it is not getting the same cold air it would as if the car was moving.

If it did, he bought crap.

Yeah, what kind of CAI was it? If there was a fan, and his car was chipped AND had a cai, but only gained 12hp... something's wrong. You should have gained around 12 from JUST the chip.

what "custom chip" did he buy? Sounds like an ebay chip.

CAI or chip are not needed for 192 HP. An OEM 325i does 192 ponies.....

what they are saying is that a chip changes a lot stuff under your hood, a better quality namebrand chip might have a better effect on the car because it's tuned to the max. look up a conforti chip or somthing, there are dyno graphs all over the web.

maybe crap.. They produce chips reading eeprom, modifing it and making dyno runs to see changes. As they say making chip for the specific engine it's possible to gain more power than with universal chip from known chip manufacturers.

are you shure that you will get exactly same power gain as in dinan or conforti advertisments on ANY engine? I don't believe it. Every old engine is unique.

I don't know how BMW is, but I do know MANY car companies claim one thing, but usually actually fall short of that claim by about 10-15%

Also, many companies will claim the numbers at the Flywheel where as the dyno shows drive wheel power numbers...

1996 318i
5 Speed Manual

Alpine CDA-7895 Head Unit
12&quot; Alpine Type-R, sealed box
Pioneer 400w amp for $20 at a yard sale (to replace my fried MRV-1507)
