My MAF is ported and descreened. I have the 160 thermo. I already use premium gas. So do you think I will have problems tunning? I am going to do the preprogrammed tunning that comes with the HPP3. What do you all think?

Thanks

 

I never had a problem with mine, but I ditched it and got custom programming instead.

 

If you haven't already purchased the HPP3, DON'T. They're nothing but $300 fanswitches. They're the biggest piece of crap I've EVER wasted my money on when it's come to my car. If you swap gears, great. If you want firmer shifts, great. If you want to remove a top speed limiter, great.

The Hypertech Tuning sucks ***, and all you'll do is LOSE horsepower. Get a good program like LT1 Edit. Not some low-rent trash like Hypertech.

 

And...keep your eye open for a cheap "stock" MAF.JMHO
