well today I finished everything up including finding out that I had the wrong ecu installed. I drove the truck up the road and had a really bad octane knock when I got on the gas it would ping really bad. so I thought great my new motor is f'd so on a whim I desided to change the ecu's and drove it again and it ran a hole lot better and no knock. the bad side is now that I put the exhaust back together I can hear the noises coming from the tranny I have noise in 1st, 2nd, 3rd, and 5th so my tranny is gonna die. I know this because a ranger I had after I got out of highschool did the same thing every gear eccept 4th shit the bed on me. so I will be looking for a new tranny.
the good side is i can crawl right up a tree, and I can spin all 4 wheels and this autozone clutch sucks so when I get a new tranny I will be buying a center force clutch. and I still have a vacum leak I have a looping idel and I can hear a vacum leak I think it may be coming from the intake.
I got the vacuum leak fixed, what a dumbass I forgot to plug the outlet that went to the automatic transmission. now it runs so freakin smooth I just need to get the other fuel line so I can stop the leak. As far as the power difference all I can say is WOW!!! I know a portion of it is the different gearing going from an auto to a manual but WOW!!!!!!!!!!!!!!!!!. I love it so I retract my statement about if I had it all to do again I wouldn't have done it. I would gladly help someone do this swap and may do it again for myself.
Oh I forgot to tell you guys but I did some lookin' while I was under the hood yesterday and I compared the mass sensors between the 3.8 and the 4.0 after I cleared the vacuum leak I started to swap the mass housings and noticed that the sensor it's self was different part # but they were the same shape so for shits and giggles I pulled them off of the housing and swapped the sensors so it is still easier to get a cone filter on and with that and the fixed vacuum leak it is purrin' like a kitten I a can't wait till sunday so I can go see how she does in the mud and trail.
