im considering going to iveytune as well. im going back and forth between ivey, dg motors(Long island), and CBRD Speedfactory in York, Pa. Ivey uses ecutek so he is the most expensive, while dg and cbrd are both cheaper because they use Ecuflash/Open Source.
would love to see the results when you get back.
even though the prokit is designed around the stock struts, ive still always heard that lowering the car will put more stress on the struts and thus shorten the life.
