i had dr p phase 2 for less than 24 hrs on my 98. 5. it was advertised to add 200 lb ft trq. my previous setup was a tm ecm and 275s. after adding the dr p i lost 7 mph on the test hill with a camper. wtf. the phase 2 probably didnt add more than 100 lb ft trq.
a local dlr bought into the dr p franchize. the dr came down and did what he said was a phase 2 and the dlr was impressed enuff with the way it ran and signed up. it did run well as i drove it. they did mine as a phase 2 and a dlr demo and neither ran that strong. betting dr p did truck with a phase 3 and told em it was a 2. thousand bucks more for a phase 3. fraud imo.
anyway,,, i took rig back to dlr and told em it lost power so they removed the dr p crap and installed my tm ecm and 275s. ran decent again but since it was a dlr that did the work, my wrrnty was voided by dc a couple years later as dc went snoopin thru dlrs paperwork.

voided for having a dr p kit on for less than 24 hrs and 60 miles. dr p stated that wrrnty wouldnt be voided with his kit and also at the time dc did say ok to do a phase 2 kit w/o worrying bout voiding wrrnty. liars!!!
also dr p states that u dont need pyro. total bs. they did nuthin to up booost and pyro got way up there.
the dr p kit is a reprogram of ecm and some mild injectors. they plug into port under dash with a laptop. i was told that if it is reflashed it could erase dr p program. i was also told the injectors they install is just 275s
what a crook. not giving ya the power they claim they do. retail 2495. 00 for 100 lb ft. [they claim 200] vs 185 lb ft trq at less than 500 for an ez
