ok so im new to this tuneing thing, I've scanned through the forums learning all about mail orders and hand helds and programs like hp tuning, the mail orders like nelson and such and such, i understand that with the handhelds you just plug and play , but with the mail orders such as the nelson tune wich i beleive im going to get what in all do you have to do? do you have to take ur pcm out and send it to him or does he send you a hand held programmer with the program he has set for you? im a lil overwhelemed by the tuning so i just need someone to help me out, and do you have to replace the thermostat like with the hypertech? and if you have to take the pcm out how hard is it to do? thank you very much in advance and i have a 1999 Chevy silverado 5.3 with a couple mods, exhaust intake and such
