Has anyone had any experience with the superchips programmer.
I'm thinking about getting one for my Denali,the website says it can add 27 hp. Sounds awesome , but I'd like to hear from someone who has used one.
DONT waste your time. seriously, it wont give you hp you are looking for. go and see allen from nelsonperformance for a ls1edit tuned, pcm. I gained .45 in the 1/4 mile just from his tune. Im sure others will tell you how good it is to have ls1edit.
a nelson tune is the only way to go man.i started with hpp3-then predator-then westers-now allan. still with allan. if you just want to go a little faster and still lose to ricers and others then go to another tune.
BUT IF YOU WANT TO WIN GO NELSON. :head:
