Well about a month and a half ago or so I took my supercharger off of my truck and I had Allen Nelson send me a retune for N/A. At the time I was planning on getting long tube headers right away so I had him tune for the LT's but some other stuff has come up here and there so I haven't gotten them yet.

My question is how far off is my tune running my shorty headers with my pcm being tuned for the long tubes?


Is it costing me some horsepower?

As far as other mods go that I have is a Vinci cam 216/224 551/551 115, CAI, 3000 stall, cat back exhaust, efans. Oh and I almost forgot NX wet kit.

 

I don't think there is very much, if any difference in your tune. I think you are ok with what you have.
