I have a 99' silverado 1500 4.8 litre with flowmaster sidepipes, intake, new spark plugs etc. suggestions on some performance upgrades? Try to keep it on the cheap side.

 

How much do you want to spend?

 

maybe under $400 for now

 

custom tune from blackbear performance

 

www.nelsonperformance.com

You should start with a tune. You can then get free re-tunes for any future upgrades you do.

 

Nelson is good, but he can get the scan cable tune from justin and be $75 cheaper when all is said and done.

i had nelson on my previous 06, and with a discounted price of $325 from Nelson, i got the scan cable from justin $300.

either way you cant go wrong. best bang for the buck

 

if i was looking at a programmer, which one would give me the best results?

 

Either Nelson or blackbear performance, stay away from handhelds
