Who is preferred for the 4v engine? I'd like to get an email tune to replace the canned SCT tune that's currently on my car. I'm thinking Justin@VMP tuning. Anyone else have an idea?

Also, I know dyno tunes are preferred. But at this point, with the mods I have it's almost useless. Plus the cost and driving 2+ hours is ridiculous. I'll save that for FI!

 

BamaChips is still a popular choice I think. I've used them on cars past, had no complaints...

 

Never heard anything bad about Jon Lund.

 

I had real good luck with RWTD...but, the best option is to get the car to a dyno shop that knows what they're doing!

 

I went with VMP tuning and got my tune 3 hours after I placed my order. Justin did a great job as usual. The car runs great. No hesitation like I had with the canned SCT tune.

 

I used ATS for a while and didn't really like them. Then they screwed up the basetune for my Whipple completely so I had Jeff Harris tune it in person. Can't beat a dyno tune.

 

I just had my 99 Dynoed and have very similar mods as you. Here is what I did for optimal performance and fuel economy:

Fuel - 93 Octane fuel economy
Fuel Load - lean 2% (made a near perfect 12.8 a/f ratio)
Timing 0-2000 rpms - advance 4%
Timing 2000-4000 rpms - advance 3%
Timing 4000+ rpms - advance 2%

 

Use on my GT and had no issues.
But I agree with Timspony , a true dyno tune is the way to go.
