DRM LT1 Corvette Tuning Part III

[@mistered9435]

I finally got my ‘97 camaro SS out for its first drive yesterday! Carl helped me out (via e-mail) early this year on a valve adjustment situation (THANK YOU). I did the full LT4 conversion, COMP XFI 292 cam, 11.6 static compression, 8.43 dynamic, ported lt4 heads, lt4 crank, 2800-3200 stall, 3.73 gears, PCMFORLESS mail-order tune, and 58mm TB. I drove it very nicely through hilly highways all day yesterday to break it in. Today, I mildly put the beans to it once, and I would recommend this combo all day long for a fun street car! Surprisingly, it has just the right amount of low-end grunt, strong mid-range, and great top-end power! It revs very quickly due to the hollow valves and tool-steel retainers. I can’t overstate how pleased I am with this car!

super sweet. your careful attention to the car and tune helps with all that good driving.

My ‘94 with Torque Head was doing the same thing with the banks being slightly different.

I’m slowly learning using Hp tuner & EEhack for my lt-1. Pcmforless did my tune & im curious. There is cats, EE flash hack & free software for the lt-1. 94/95 free scan was the first live data for me. I’m glad someone else is posting about live data & programming so thank you. She does sound yummy 🇺🇸

[@EllweinEngines]

Fun to learn!

My torqhead was ok could never get bit tuned correctly so I sold it. Going holley terminator x

[@EllweinEngines]

The Holley Terminator X will be good. And if you have questions there are so many people that can help.

[@jarmaljackson]

@EllweinEngines okay, I appreciate it.

Car has some rare wheels

[@EllweinEngines]

really. People keep posting about that. What are the wheel's history?

[@raymckinney604]

@EllweinEngines Dymag made them back in the day. They are made out of magnesium to be lighter weight. The last set I seen sold for around $4500 a few year's ago.

[@EllweinEngines]

@@raymckinney604 holy cow I better keep my garage doors locked. They sure look clean and tasty. I like em.

Unrelated but something ive always been curious about. For a 93 Corvette with bolt ons would an adjustable Fuel pressure regulator modification be used to increase horsepower bc the speed density system wouldnt try to correct af adjustments?

[@EllweinEngines]

Interesting. I don't know for certain. If it needed more fuel that would be one way to do it yes.

Im currently building a 67 cutlass and i picked up a 97 lt1 and a t56 trying to figure out the best way to tune it for a cam and head job only build any idea?

[@sstevocamaro]

You need Jet DST. That’s the only software that can tune a 96/97 LT1 PCM. It’s $575 dollars. If you use a 411 PCM you can use almost any software out there.

My camaro ss is a 1997, and Keith at pcmforless had NO problem doing a mail order tune! I think he charges $300. My tune turned out to be perfect as far as I can tell.
