well i put the ls1 hot cam in this last weekend and boy was it fun it fired right up on the first try........ but now it is a real dog its like driving a terd i dont know wtf i need to get it tuned!!!!!!!!! i have ls1 edit already but dont have a clue where to start drove it like 50 miles figuring the comp would learn a little did learn some but not enough no clue where to start.... i already looked in the ls1edit.com flash files for a tune i lwill look at those to get a idea but if any one could point me in the right direction i would greatly apreacate it btw its a 2000 4.8 auto and it sounds really mean at idle but cant back it up my guess is it runs like a 20 sec 1/4 mile oh let me get this straight you put a cam in to lose hp right????????

thanks for the help

 

You have any sound clips with the cam in? I've got a 4.8 in my 2001 and was thinking about putting this cam in over the summer for a little bit, due to the fact it won't cost me too much for now.

 

That is a lot of cam for a 4.8. You definitely will need a tune and a stall. Can anyone help with the tune?

 

Oh yea you will!!!!!!! A loss of some low end comes with the territiry with a cam like that. Especially in a motor smaller than an LS1. You lose some low end to gain mid and top end power. Thus where a higher stall verter comes into play. To make up for the loss of low end.

 

Not trying to hijack, but as stated earlier I've been thinking of this cam for a little while. I know I'd need a tune and have figured that in with the price, but I wouldn't necessarily need a stall unless I wanted to take full advantage of the cam, correct?

 

I have this cam, and yes it will be a pain (my experience at least) to work with. I need to still iron out a few tuning issues. For the time being, just to get yourself from point A to point B, flip the "set idle screw" on your TB around so you can access it from the top. Then crack the blade open a little bit so your motor can idle better.

I didnt lose any HP or low end torque.. if anything I gained low-end torque. I do have a 3000 stall though.

 

I had some tuning issues too. I have a nelson tune, and it took a few iterations for him to get the idle issue down. I didn't notice a loss in low or high end. I have a stall though. It has a helluva lot more power all over the rpm range. Its a good bang for the buck cam kit. I think I have a lot of power still left on the table though, because I don't have headers to take advantage of the long exhaust duration.

You might consider a nelson tune, and use edit from there. But dude, come on....20sec 1/4mi....that's terrible, even for Tucson. You shouldn't run that stock, unless your truck is f'd up to begin with. Anyway, good luck!

 

How do you like the lope with that cam?

 

You need a big *** stall, and some high ratio gears in that beast. Otherwise it'll take forever to hit the sweet spot.

 

just installed a tr224 224/224 .590/.590 114lsa in mine this past friday, tuning wasn't that difficult. If you need help I would be happy to. You could email me your file if you like
