[QUOTE="Big Bore, post: 351856, member: 760"] That's no different than a stock motor, so why don't those blow up? The only reason IMO that this is an issue is over fueling down low. That's one of many reasons why I prefer the stock fueling at the beginning of the pedal. The lurchy, over responsive throttle from some tuners is a false sense of gained power, makes DD annoying, the cruise control useless, and is dangerous to a cold engine for the exact reason stated. Too much fuel too early is a major flaw from some tuners. The guys keeping motors together at higher HP numbers are moving the power up the rpms. There have been several good threads on this recently. PontiacRoss making over 700HP and revving all the way to 5K rpm on a stock forged block. Curtis making 400 on PMR's with 250/200's, and I bet that motor lasts for another 100K at least because he keeps stockish fueling on the bottom. I admit it takes some time to get past the "dead pedal" feeling after having the lurchy overfueled tunes, but once that passes you won't want to go back because you begin to realise it's not dead, it's smooth and linear and predictable and you still have full power when you bury it to the wood.
