www.thefastman.com if you want the stage 2 chip to go with the tb. then get it. my buddy has a stock 4.7 with only an ibtake and exhaust in his ram and he has seen gains also but not like the dak because of the weight issue.plus it is 20 degrees out and the cooler weather has some affect. it will be better once it is warmer, lets say 50/55 out
yeah, I need to check the last statment. its the spacer. people say it does nothing... but the producer claims 10 hp... so its up to you on the spacer.
I have also heard that you will trip codes with the T.B. if you dont "properly" reset the PCM...
I kind of thought that that's what you were thinking. I've heard both positives and negatives about the tb spacers, but I've heard a lot more of the negatives for our trucks.
