problems with new combo.. minor but still

ok heres the deal i have the 306 with edelbroks and GT40 intake.. well the car just doesnt seem to impress me much it doesnt quite have that seat of the pants pull to it i was hoping for. the car is 5speed with 4.10's it wont even spin off a roll in second?. wtf I think something is holding it back.. now i know i have a bad connection (dirty connection) on my mass air meter and something is throwing a check engine light in but the motor is PERFECT so its gotta be in the EFI.. help me fix this thing cause EFI is the ONLY WAY TO GO in my book..
