Went to the dyno today and could only muster 302hp 316tq with my mods: Hotcam, ported heads with 2.00in 1.60ex valves, SLP headers home made CAI and Flowmaster exhaust. What a dissapointment to see a stock LS1 put down a coupld more then me and another with headers, CAI and cutout put 350rwhp.
Seems futile to put more money into the motor.

 

there is something wrong with your car.... those numbers can be acheived with bolt ons. I am close to your rwhp, and over your rwtq, and I only have shorty headers, and not ALL of the bolt ons. Fix your car... if it was running right it should be putting down the same numbers as that LS1....

 

you need to get your car tuned, you'll easly pick up hp

 

dont give up on it man. u definately need some sort of custom tuning (PCM4less or LT1 edit). u will pick up a ton in tuning!

 

I failed to mention I have Pcmforless chip.
I checked this morning and number 5 spark plug wire is burnt.
I think I may need to upgrade my injectors, get rid of my CAI for a quality unit and get another chip burn. On 93 Lt1s can I use my OBD1 diagnostic to save data and send it to pcmforless? Is there a special cable available and used for this?
