Yeah the times sucked but it'll get better, I promise! It's all in the tuning (or lack of it), and I'll have before and after track times once it's running right.

 

Old setup was superram-LPE 219 and new is HSR-230/236? Any chip work on the old setup?

 

Wow, you must have some little electrical gremlin hiding in your engine bay somewhere like you said. I'd check out your distributor and the entire fuel system. Your car should be running at least as fast as your old setup even with the same tune. JMO. How's the low end compared to your 219 setup? I bet you'll miss some of that tq while driving on the street.

 

Yup, new is HSR and 230/236. My current chip is setup for my old ZZ3 cammed motor and 22 lb injectors. I used this same chip with the SR-219...it worked better on that setup than with the HSR-230, but not optimal for either one. This weekend I start digging deep into computer tuning.

 

I agree it should be running almost as fast with my old setup. Keep in mind though the time in my sig was at a different track on a 50 degree day and the time I ran with the new setup was on a 90 degree day. I talked to a few guys that day who said they were running about .5 sec off and 3-4 mph slower than normal.

Below 3000 rpm the SR/219 has better torque, but I think once I set it up correct it won't be noticable at all.

 

What RPM are you shifting the new setup at? And what rpm did you shift at with the SuperRam?

With the old setup I shifted at 6000. With the new setup shifting at 6400-6500 produced the best et.

 

once you get that HSR and cam setup tuned correctly youll see a big improvement.you might want to advance or retard the cam timing slightly (DEPENDS FACTORS LIKE, your engines displacement,stroke,cylinder head flow,STALL SPEED,ignition curve,fuel map, AND GEARING) but ive found that 36-38 degrees total ignition in by 3000rpm and 4.11 rear gears with a 3200 stall works extremely well on several corvettes running the HSR
