Hot damn vs KEM 345

Well guys not real sure how to judge these two. I have been running the KEM 345 for a couple of days and not as impressed with it as I thought I would be. Kinda thinking the hot damn tune might have a little more a** to it. I was thinking the 345 would be a huge difference compared to the hot damn which is advertised at 250 or 275 depending on who you ask. Don't want to knock it to soon, but thought it would be a little more out of the box. Seems like it just falls over when the torque converter locks outs. It's starting to shift better, but really was hoping for more.

345 isn't a "race" tune it's more of a high HP daily driver. If you want a kick in your pants run the 310 and you'll notice a huge difference

Both of you are very correct. It doesn't prove to be any stronger than a 275 tune. I switched back to my spartan 275v3 today after driving the 345 for a month or so. My shifting is back to being precise and snappy. The shifting is so erratic on the 345 for easy driving. My rear leafs constantly clunk when truck shifts from red lights at light throttle. It is a good running tune engine wise but the shifting needs some work. Mine will also kickdown after the converter is locked after 45mph, never had any other tune do this. I have not seen any dynos of the 345 meet the hot damn much less the 310!

I hate to say it but I am a little upset that I spent the money on it. Was definitely expecting more.

Dyno numbers say a lot if your comparing power.

Hot Damn did 556 on a truck and the KEM 345 did 530. The numbers speak for themselves. The dyno used was one of the most respected in the country, which says a lot in my opinion.

why don't you call Mike first , and see what he says? he can change the lockup and make it higher besides something smells fishy here, shifting erratically and the KEM 345 have nothing in common. Just give the man a call he will fix you up, and then report back
