i dont have too many mods done to my evo yet. just intake/turboback exhaust/springs. but in my experience buschur has not made me very happy. i have called them in the past to try to get information and reccomendations and they have not been very helpful. I have had great experiences with IPS. Brandon, Mike, and Jeff are great. they dont mind gettin on the phone and giving information, talking about plans, and giving recommendation. I will be taking my car to them in the next couple weeks to get the 60k service along with other goodies. Slowmotion has been good too. I took my first 240 there like 5 or 6 years ago when they were still on westerville road(VERY OLD SCHOOL!!!!) they helped me with the sr swap.
