i have a 1999 comaro i install mti stage 2R heads and lg x3 cam on my 5.7 engine i have also ud pully and k&n filter and borla catback and MSD coils

all what i get on the dayno is 330HP and 312TQ


need some thoughts

 

it hurts to read....but...

what kind of dyno?

What was the DA when you dynoed?

is the car tuned?

 

what is killing me that i swaped form patriot stag2 and mti r1 cam and the car was running 393HP and 380TQ

its a daynojet and the car is tuned

 

hesham do you have your dyno graph? the old one and the latest,maybe it would be understandable if you show it.

 

no but i can get it tommoro i will change the MSDs and return the stock coils

i have a 280 PSI fuel pump and 30# injectors my timing is around 23#
and i can't go higher becouse i will have konck.

my A/R ratio is aroun 13.2 its not that lean but i dont know it is the problem

 

i found my problem it was the MSDs coils i will post my dayno with the MSDs and after i removed them

and when i finish my tune i will post my final results

 

i have 1.75 rockers should i install them?
what about clerance?

any thoughts?

 

so is here any one have the knoledge to answer my question?
