Speedchips isn't very smart. The stock EEC will learn and adjust for the new injectors/MAF to make it run right, but only if the parts are correctly calibrated. It actually does a great job of doing that. You can't even re-program the EEC...that's what custom burned chips are for. 24s are too much for what you have anyways. I agree with the previous...get an adjustable FPR and lower your fuel pressure and make sure your MAF is correctly calibrated.
