yea a simple wet kit is easy to do a basic tune yourself, just go do dyno pulls to see your AFR through your band..$40-50 for your average 3 pulls 4pulls if your not annoying and bring food! lol..if the reading is too rich go with a smaller jet and vice versa when its on the lean side of things...get atleast a Fuel pressure gauge inside the car if you cant afford a Wideband so when that pressure drops better let dat bitch go!! lol..but yea goodluck with your shit i got a friend spraying 75 with a wet kit on his S2k tuned and its still running fine for the past year and half
