I have the VR + Power Duct on my 02Z.I like it very much and it seems to be very effective.Dyno testing ( since the car isn't moving) will not show any gains.

IMO,well worth the $ and the PITA install.

rat454....I have the same model Predator as you do and I'm a very satisfied customer.My tune is on an 02Z06 Vette rather than a truck.

I got the 15-20 hp I expected and was able to turn off the cags and adjust the fans to my liking.Also,I received very good email support on this forum to help me ...

Thanks & Done.

On a 40 mile interstate trip today( 75mph/1900rpm),the first 5 miles were
(T)+4.69 and (B)+2.34.After about 15 miles,both settled on +3.91

Am I getting close ?

Thanks for ALL your help!

Nope,all tight and taped at the connecting points to avoid air leaks.

After I installed the VR Power Duct,I was popping lean codes fairly often.The Halltech screen eliminated the codes and made the throttle res better.

Car runs great...good power and mileage is decent.

Any suggested adjustments ...

This is dbaker from the CF.02Z06 Corvette with VR + Power Duct + Halltech Honeycomb MAF screen.No other Mods.

Just did 2 ,30 mile data collection runs using the older model(2.13),no logs.First run was at approx 40degrees at 58mph:Both LTFT's ranged from 15-23 and on a flat surface was 21 & 17.Map ...

I wanted to increase my 02Corvette Z06 timing ( performance tune installed) about 1-3% .See any problems?

Thanx

I assume it's unlocked.

version 2.13 and it is unlocked.

Thanks

Looking to tune 02Z06.

I might buy an older model of Preditor.Are the older tune files the same as the newer tune files for U7198?

Thanks
