Yeah my car when I hop on the gas feels like it wieghs about 12,000 pounds. Its terrible and I just can't figure it out because it should be able to shred the tires. Once I hit about 2800 RPM the tires break loose a little and it takes off and its really pissin me off.

its like I already have said, the speed density ECU programming is based on the stock cam and its lift and duration numbers which have changed since you installed the 1.7 rockers and this is negatively affecting the fuel/air mix and timing the computer is using, even at WOT when it ignores the O2 sensors and go to fixed maps in the ECU for injector pulse width and timing settings which are still based on the stock cam and other stock parts. the only real fix is a new chip and dyno tune if that is possible with the SD system you have. you might have to switch over to MAF in the long run to get the correct tuning ability to go with the mods you have made already before the engine will pull well from idle up to WOT when the computer goes into open loop mode.
