hey guys i put 5 tunes and a dsp5 switch in a guys truck from my area. i go through rob but this kid wanted a lope tune so we went with a different tuner. i will leave it at that. the stock tune copied fine, got 5 tunes and they went in fine. the switch is working fine also. problem is that tunes 1-3 act about the same. and they shift funny too. hard to explain the shifting charactistics but its kinda like it wants to defuel in between shifts and then decides not too. tune 4 is a nightmare. its supposed to b a lope/race type tune. if u try to take off from a dead stop the throttle pedal does nothing. wierdest thing ive ever seen. but if u get going on another tune and switch back to tune 4 it has throttle then but only above like 20mph. tune 5 is a max effort type tune and it seems to run ok but i think it should have more a$$ than it does. it flares alot on shifts in this tune also. its a stock trans truck and if i turn tow haul on it shifts alot better on tune 5. so im chalking the flares up to it being a stock trans and not liking the power. i had the kid come over tonite and was log a run or two but when i plugged my v2 in it had no power. i just read that it could b the cig lighter fuse. this truck is an 06 lbz with like 150k on it. we really have no idea if it was tuned before or not. if it was tuned already and then i put efi on it would it act wierd like this? im just over my head i think. i can install a switch and throw tunes in a truck in my sleep but when problems like this come up im baffled. i have an email in to the tuner but havent heard back yet. thanks for any help or insight u guys can give me.
