A great new/ old tuner to consider - ZR-1 Net Registry Forums

jonszr1 · 12-18-2006

I went down to texas to get my inj housings ported and a new chip burned. Corey Henderson in the midst of opening a new business (henderson performance technologies)took on the job. I started with 370.83rwhpand 350.76 tq. this out of a 121k car with jeal headers flowasters ex. rc inj and a chip from another zr1 tuner. after the porting but before tuning 394.6 -363.8 then Corey did his magic final results 409.9 rwhp373.66 tq. what made it all the more special is i got to help and learn while pulling off and putting on theinj housings and plenum. he also did something no one else has( I tried 4 different tuners in la) getting rid of a detination /knocksensor event @ 5200 . He did this on what he didn't know at the time 89 oct shellgas (Sorry for fooling ya corey)hehe. His price was under 1600 out the door. So give thought to him when ya want a dedicated Zr1 mech or tuner. I decided who is doing my 368. Good guys are hard to find to work on our cars. With pride I would like to add him to our list. 409 she is very very fine

Corey is known to a good number of ZR-1 enthusiasts. Though he does not have the number of custom chip/tunes as some others, he has a good reputation among his customers.

i had allready voted on this earlier . can i change my vote. I believe Corey now has every type of tune in his file. Allthough he prefers to tune the car. His price to tune my car inc prom was less than i paid for a prom bought over the phone for my car after I put headers an exhaust. Don't get me wrong I am in no way knocking anyone else. Just think its cool that we have another quality guy that works on our cars. Thanx Corey Great job.=D> Oh yeah Corey When ya want the red car for a368 upgrade.

Just curiious, JonsZR1, does your Z that Corey did the work on have ported heads ? If not, that is a butt load of RWHP for top end job.

nice #'s

jonszr1 · 12-20-2006

Yeah it blew both coreys and mind. we had 396 after porting but with the old prom that was set for headers and exhaust. then corey tuned a whole new prom and funny enough finished @409.99. this with122k on the motor Coreys ph#(210)867-6286 If ya would like to find out abou it. I don't have anyway to scan the dyno sheets. I only have a lap top. He definatly is na guy to think about for .his mod .But after seeing the increase by tuning the car not just a pre made chip for the mod i would say make sure you get a tune for you car.blew my buddys mind with the 07 z06when he only got me by 2 cars.

No head work & no re-degreeing of the cams!?!? Jez-us that's some sweeeeet numbers! Nice of Santa to bring ya your present early.

jonszr1 · 12-21-2006

Thanx, But i didn't know santa was 6-2 and 31 yrs old and also living in New Braunfels, Tex. I really think it was the dyno tuning done after that got the numbers up there. we started at 396 then Corey started adj fuel (more)and timing(less). highly suggest having someone fine tune the car if you do the ported mod mine gained 13 hp 12 tq. by dueing this. Now i want to get a K&N and an x-pipe and see what happens then.
