Can anyone recommend a good chip for a stock 91si? I do not know much about them and would like to install something nice.
Stick with stock ignition unless you really want to go wild and build up the engine for high revs.craiger21122 said:I was planning to put a little work into the car, specifically the cam, intake and exhaust, as well as the ignition system. After that then I might try a chip
I am not a tuner but have heard tons of stories about "performance chips"... the latest by my nephew who dropped $235 on one for his BMW. At first, he claimed it was great (who wants to admit a $235 mistake). THen he realized his fuel mileage dropped, his engine did not run as smooth as before, and he had no proof it actually increased performance. Just wait until he tries to pass emissions. I suspect that the chip is just running him richer.Synoptic said:As a tuner, I would not reccomend spending money on modding an ECU for a stock motor. IMHO, it is totally worthless. Put some CAM or forced induction device after that, tuning your ECU will be mandatory.
I do agree that a chip for our cars is pointless when stock. But some cars do genuinely benefit from being chipped. My friend's VW 1.8t is a perfect example. The car pulls much harder than stock and is definately much more fun to drive. Low RPM drivability didn't really change much making it easy to drive for the most part. And his fuel mileage has stayed pretty much the same.Charles said:I am not a tuner but have heard tons of stories about "performance chips"... the latest by my nephew who dropped $235 on one for his BMW.

Not only benefit, but aren't you asking for a damaged engine without it?d16z6rex said:generally, stock turbo cars ar ethe only ones that benfit greatly from chipping.
and Gain +/- 5 HP more than the mods already give you.daveb91 said:Like I said you could just tweak the fuel timing a little for basic stuff like I/H/E and do the launch control. :evil:
