I've been in contact with (2) speed (tuner) shops while looking for a dyno tune and they advised me that the older model evosport shorty headers will not give much of a gain with or without a tune, and that I would have to go with long tubes before I do the throttle body upgrade. I was also told in order to do the TB upgrade That I need to upgrade the injectors (along with long tubes) so I will not blow out the #8 cylinder. He said that they wouldn't even dyno my car with the shorty headers with the larger throttle body because he has seen major damage done to the engine without the complete (injectors, long tubes, 80mmTB) upgrade. The frustrating part is I've been online researching all the upgrades and piecing the MODs together for months now to find this info out. The question is has anyone had major issues rolling with shorty headers, do shorties limit the mods you can do? Also I have a VRP crank pulley with the part# 318200175 not quite sure if this is a 175 (because of the last 3 numbers of the part number) or is it a 180?

Thanks in advance
