Len.. in most cases cars are fine, but occasionally cold start/idle can be an issue. I guess this is the bad thing at times when a customer is far away.
There where no issues with knock on the dyno or road test with your car that would result in the low MPH you mentioned.
did you get the HP Tuner to log yet?

My old setup was a stock 346 with these heads and trv 3 cam and stock ls6 intake!
Speed inc tune it .... THen i made a *** of myself on here cause it ran poorly after i got it home . Before i looked into it further i wanted to throw blame. Come to find out have quite few issues that need to be address. old setup made 414 hp i think?
Larry might still have a graph laying around!
Oh I took the 4.11 out and went back to 3.42 just because I also put a m12 6 speed in it with taller 1 2 4 5 6 gears . I was just blowing the **** outta the tires and no really point in racing ..lol lot of fun but pointless with the stoker in her and taller tranny gears.
I have few issues with the car now just very very minor stuff and Larry said he would take care of it .
But the car pulls like a train wait more like a diesel with a 600 shot of nos on it!
Thanks for the compliments Guys ..... Hopefully my luck is with me instead of against me this time
Also about doing something right !!!!!!!!!!! I read every single post on here with guys and 402 and 408 with the bigger cam .... and predetor z and patrick g convinced me bigger isnt better. Everyone told me when i was putting this cam in it wasnt right . But **** its making as much if not more than the bigger cams and still managed 19.2 mpg on the way home from speed inc. that was with my buddy nate driving it at 75 to 85 all way home.
There are so many post on here about cams and heads . So many people talk **** about tsp heads and told me to go with afrs and other more exspensive heads. But I think i did alright with what i have and I am happy with it .
I know my car isnt the fastest car or best lookn ,,,,,,,,, but **** ,,,,, i did it!
God I love the ls1! Cammed make me a offer! Its all just sitting here!
