Thanks guys!. The flame war hahaha!. The car was tuned by rpm in delaware. It's not 100% great.. but wide open throttle is better now.. idle quality and part throttle isn't right yet..I can't wait to see your car done SIXTy5

Yea thought it looked like GB in your pictures, I'll have to try and catch this thing at a show or the track if you have it out. I'd love to see it! I had planned on taking my car to RPM when I'm done, did they just not get the tuning done in one session or just drop the ball all together? Couple guys I know use them and I haven't heard any issues. My cars still a ways away from being done so I'll have to keep an ear out on tuners. Don't really have many ls tuner options around our area, atleast that I'm aware of, although this is my first jump into the ls world. Keep us posted when you hit the track, would love to see what she does.

thanks xsboost,.build is looking good so far!! rpm dropped the ball alltogether,the tune wide open is good, bud idle and tip in and part throttle is not even close..since i picked it up..im hoping its just a sensor issue coincedentally. so untill i find out if its the tune or not i wont say that they are to blame. i think the contact/up to date portion is lacking on their end. they had the car for almost a month. But i dont have the typical stock pcm. im running holley efi so i guess its a little more complex. so for now im replacing all the sensors and seeing what i get and then working on the idle issues.i have many people that have went with them and had nothing but awesome service and quality.im just that one out of 100 i gess
.im hoping to dip into the 10's on motor.we will see. i do have a 416 ls3 boost motor waiting to go in hopefully end of summer next year

I wouldn't think 10s would be an issue for that car, you've got a solid setup! Ewww 416 you say?! Spill the beans on that lol. Yea I realize every shop will have their few hicups with cars, no shop is perfect but how they handle the situation will say alot. Guy I know took his camaro their on a wednesday morning for heads/cam and tune and picked it up Friday morning good to go. Hopefully you get her dialed in so you can make some passes in it before it goes back under the knife!

I used 69 camaro headers. And modified the primary tube on cylinder one 6D9... I have a 92 mustang subframe in the car, and I'm using aje mounts.. thanks EricL. The setup is basic. L92 shortblock stock/ holley hi ram/ 235-239 cam/ 255 prc heads.. my other motor is a 416 set up for billet 88mm turbo and about 18-25 psi but for now I'm going to run my 6.2 set up and see what's up
