what i get from reading is that he had it pullied for 20... Bought heads and cam and it dropped to 14 psi because of the efficiency of the motor. What is going on with the tune is anyones guess and there could be several hidden factors. Lets say, he has 19.x and now he has 14.7 psi showing. Thats not an unrealistic drop if someone put on some race ported heads that flow 315 cfm
plus it could be std.
who cares
BTW this car needs an AUTO with a 3500+ stall depending on gearing. i would not put a t56 in it if I planned on making any more hp than you already have. Id rather run a 9.90 at 140 than a frustrating 10.8 at 135
Good luck and enjoy
