Another successful story...
A fellow member of the corvette forum had contacted me a couple weeks back about retuning his 200x Z06. He complained about driveability, idle and lean issues that existed after one very well known florida tuner and a somewhat well known tuner from down south. Basically the car wanted to surge pretty bad @ idle and buck under cruising in the <1800 RPM range. We had talked about letting me tune the car and as always if your not happy with the tune you we don't charge you.
We got started about 12:00 and installed the wideband and started setting up my custom tables. I upgraded the Operating system to Real Time Tuning so I could show him exactly what we changed and how the car responded. Well after we tuned the first table and set the base parameters driveability was 80% better. No idle surging, you could cruise @ any RPM down to 900 and felt smooth, and WOT fuel changed from 14:x to 12.85(slightly rich for road racing). Needless to say he is very happy with how the car drives now. I guess it goes to show you don't need a dyno to perfect the tune.

Hi all, I am the owner of the car Phil is talking about. Phil pretty much hit it on the nose with the before and after.
I really thought I went to big with my cam choice (F13 230-232 595/585 112) and even started to dread driving my car, but the 40 minute drive home after my Phil tune was really enjoyable even though I hit heavy traffic, infact I cant wait to go for my next drive. The difference is really big and now I know why people say the tune can make or break your cam choice. The price of the tune was worth every penny.
Thanks Phil, I have falling in love with my car again.
