Power from mods without tuning ?

SUBY2.5 · 09-08-2005, 05:35 PM

I am just wondering If any one has dyno'ed their cars with out computer tuning and actually seen much difference diiference from stock #'s. Is it really worth modding the engine w/o ecu tuning. Thank's, Joe

As much as I hate this magazine, there is an import tuner article about the STi that dynos a car with only a turbo back exhaust and tumbler deletes and claims it makes 330hp in that configuration. They then go on to tune it and pick up huge torque gains in the mid range power and some decent top end too. But then it is import tuner so take it with a HUGE grain of salt. But I dont doubt that the stock Learning computer can tune itself over time for a higher flowing exhaust. Probably aided by resetting your ECU first.
