How many times was it recommended by various people in here that you get the truck tuned after the supercharger install? I don't mean to get on your ass too much here but we don't give that advice for our health. You need a tune because the calibration of various things will be out of whack now that your s/c is on. While Ron is a nice guy and can do some decent machining I don't believe he has any custom tuning experience. The fella's here that recommended that you get your truck tuned, including me, do. Just because someone else "has done it" doesn't mean that it is a good thing to do. I have seen guys running 500+rwhp on a totally stock 4.6 V8 SOHC engine. They were very very lucky but that doesn't mean that you will be.
If you pay attention to the advice that we give you in here then you will not be lead astray. There are some of us in here that have been doing this stuff for many many years. We are here to help you attain your goals but if you decide not to pay attention then don't be surprised when you screw something in your truck up.
If you are anywhere near Alabama then give James a call and have him take care of tuning you. If not then find a local SCT tuner who has a good reputation and have them tune your truck in person. The cost will depend on what the tuner charges, how long the tune takes, and how much the dyno shop charges for dyno time.
Just noticed this post and want to clarify a couple items. Lifted 4.0 was told by me: He would be able to use stock tune to get vehicle running and tested without throwing a cel, provided: The stock 24-lb injectors, maf, 3.18 stock supercharger pulley is being used. He was also instructed to not push top limits of boost till he got a tune as it will lean out at top torqe/hp as I found on my first dyno run. I put the prototype on my vehicle at 92,000 miles and now have over 186,000 miles with no problems to date. I did put about 1,000 miles on it before I did the 2nd dyno with a tune for fuel and shift points only.
ROCKET 5979 is correct a tune is a must and I totally agree. The biggest problem is very few know what they really want and think more hp is better, but are not willing to do their homework!
heyy, soo really looking to get the IAT hooked up, and jah#### forgot the number, said that the manual will help me locate those wires, soo i will look that up, but i am planning on going to get it tuned this week, thursday probably...
while hitting high levels of boost, ABOVE 5lbs, will not having the IAT on the manifold throw the check engine light, because as ron said, i shouldnt of been putting the pedal to the floor...but i did go out and test it pretty hard the day i put it on....
sooo really im wondering..is the PCM sooo confused that it doesnt know what the temp is that it will screw up the A/F ratio??
thanks

Then I'd say you have a vacuum leak!yaa i tried that, reset it, and didnt even go into boost and the CEL came on 8miles later
and the manual doesnt say anything about the IAT connections coming off of the PCM....soo i think we have established that its the outer 2 wires, but which do i connect where is the question...there is a black and green wire coming off the IAT sensor on the manifold i think, soo one should be ground and the other??
soo do you have any sckematics on what wires go where on the IAT?? cause ron didnt know what wires went where
Can anyone help him with this wire connection? Poor guy has been asking all over the place lol. Wish I could answer that for you bud. I still think the sensor has no polarity so the two outer maf wires might go to what ever wire you want on the iat.
My post 70 and emails with pic's sent to him all indicate 2-outside wires?
