i just got my LE2 HCI installed on my car and it only put down 297 RWHP on the dyno????? i did about 70% of the work and let someone else finish it off bc i work out of town a lot. the guy that tuned it is named chuck, a very well known guy. we hooked up a tech II to the car and found out that #1 and #5 cylinders were missing bad. with those two cylinders missing could that be where all my hp is? also the people that finished the car set the rollers at 0 lash and did 1 full turn on all the valves, is that too much, could that be where my hp is too? other than the missing the car seams to run good and i have new msd wires and ngk spark plugs that are on the way to see what happens.

 

There are a lot more factors that come into play...

Tell us exactly what all your setup is- bolt ons, fuel system, stalled, etc. etc.

 

full bultons no cats, 30lbs, 52mm,3:42 auto, 2500 stall, 1.6rr HCI.

 

I would let Chuck Anders tune my car anytime, Need to find out why your missing on 2 cylinders (i see you are) 297 on a 6 cylinder is basicly what your running

 

not bad #'s on a 6 cylinder. the guy that finished my car put thermal wrap on one of my wires and i have not checked it out yet but pritty sure he burnt up the wire. chuck said its not the opti and it is just in the plugs and wires

 

I would definitely check those wires, if there not ran perfect you usually know not long after you get it all back together

 

just checked them all on the ds and 2 are burnt up badddd

 

does anyone know if one full turn after 0 lash is too much

 

Depends on your lifters. For the LS7s (OEM replacement) I had best results at 1/4 TPZL.

 

they are ls7 lifters.. how much hp is lost with them being that tight?

 

If they are too tight, the valves will hang open and you lose compression. Substantial power loss.

 

ok ill back them off 3/4 of a turn

 

fixed the plug wires and it did 323rwhp at first and then after the tune it did 360rwhp and 323rwt. it seams kinda low any opinions?
