allen and i took her to the street for a retune after a 4" diesel exhaust threw my tune way outta wack. i was running the 5# spring that would net 6#'s. after the tune it felt stronger and still was learning.we decided to dyno since there wasnt much going on after murderedoutgmc's truck (nice to meet you by the way)was coming off the dyno. strapped her down and could only get like 430 hp...worked on it and still with the same result....put in a 8# spring that netted 10#'s and let it cool down some. got everything going and netted a whopping 100 hp more with only 4# more boost at like 526hp and 533tq and this was on these heavy *** 20's as well...we only took it to 135 mph and the hp was still climbing...i told allen that was good enough and unstrapped off the dyno...thanks again allen for a great tune and the awsome power..here is the sheet:http://www.ls1truck.com/upload/files/105/dyno.jpg
