Gotcha. You could mail him your PCM and specs. He can flash it and mail it back. Just trying to give you options...
Good luck!

So you couldn't just flash in stock 5.3 tune to the 98s?

I personally don't, had my tuning done by someone else with hptuners

i actually dont mind 98's... alot of tuners talk crap on them, but they are so simple they have less adaptives which makes your changes "stick" better if you know what i mean
