Ordered some parts for my truck inputs

Ordered:
snow performance stage 3
3.75" Pulley for the whipple(Has 4" pulley right now)
This parts i ordered today so i already had the nelson tune and injectors so dont know if i should send my pcm back will it make a noticeable difference or not that much. I think my pcm was tuned at 6 psi and my truck only getting 4. whipple told me it could be my elevation or the size of my engine giving me only 4. SO the tune is fine when i get the smaller pulley it is supposed to get me to 6 psi. Just the methenol is not tuned will it make a big difference is it worth being without my truck for a week and the charge for the re-tune.

I would let Allen look at the tune just to be sure.

With the meth kit, you should be able to actually add a slight bit of timing since your IATs will be lower. But Allen is the tuning master and he will send you a mail order tune that will be great and safe for your FI motor.
