8Adrian15187"it was easy to install but tunning is a bit challanging. Afrter i got eaverything diald in it performed very well."
8Alex20250"Great part had some trouble with install instruction might have and error in them. I folwed the external wastgate setup instructions but was un able to properly controll my boost. Switched the lines to match the internal waste gate setup and no problems what so ever."
9Adrian"had it in for a week now works ok still dont have it fully set up easy install"
9Joshua16639"thanks for everything, make sure u send for instructions in your own language"
7Yamil15129"Not easy to tune unless you have wide open space or a dyno. Once tuned it performs great. High and low settings are great to toggle between especially if girlfriend decides to drive."
5Dave10077"Easy to install and fairly inexpensive but the praise ends there. The instruction manual is filled with errors. I had to resort to going onto various internet forums to get clarification on how to actually set the unit up as the manual's references to which buttons to press are wrong. The Profec B Spec 2 also has software bugs. The warning feature does not work properly in HI boost mode. Finally, the buttons are tiny and hard to hit while driving. The display is good but only if it's pointing directly at you. If your viewing angle is off by more than about 15 degrees, the display gets hard to read."
7SpillmanSr10291"I haven't installed this product yet, but one thing,I can tell you. It came on time, brand new and what I expected."
10Steven10187"On a Supra it increased power out of sight. I draged a v8 holdem statesman and gave him a good head start. I past6 him as if he was standing still. To my amazement I didnt realize i was still in low boost mode and never went to high boost. his is on a stock tt motor 1993."
10Jason6219"Very very nice. Easy to install and works perfect. Turbo response and and a steady boost level is a huge difference over MBC. Also has a built in boost gauge that is great."
5Fred71216"It was easy to install and works well with low boost, 10lb wastegate spring - 16 lbs boost. When you try to take it up to 18/19/20+ becomes very unstable. It does not hold steady boost like at lower values. I am changeing my spring to a 15lb. I hope it will run steady at 25lbs. If not I am going to go get something else. If you want it for low boost it is a 9 but if you want run high boost only a 5, that high mainly because of the other options that are on it."
9Doug"First of all Greddy makes great products, it was easy to install and once I read the instructions a few times it was easy to adjust. So I don't know why anyone one rate this produt so bad. Also thanks to for all the info."
10RaymondC4342"Great bargin works as advertized"
7Daniel4118"its ok, we had some problems with it in the beginning but they have seemed to work themselves out."
7Thomas2330"The EBC works pretty well, but I had to mess with it for quite a bit before I figured out what was going on. It didn't help that I had no one to use as a point of reference since I was one of the first owners."
