Retired LEO meow
I have a question that someone might be able to answer. The 2004 GTO is slated to have 350 hp and 365 torque. Does anyone know what that will translate for rear wheel hp and torque?
Don't waste your cash on shorties, LS-1's do very well with LT's. (At the mercy of the aftermarket) You are correct on the t.b.TprGTO said:What manufacturer would you recommend for headers, intake and exhaust for the LS1 in the GTO? Looking for performance gains, preferably low end power. From what I was told, a throttle body will loose low end, but make it up in the middle to upper power range. Is this true? Any input is appreaciated. Happy New Year All!!!!
LS1edit will be availablels1builder said:The only limiting factor is how easily tuned the computer is. I don't know if it's the same PCM used on the previous U.S. LS-1's but PCM tuning is a must for a cam change.
