Ok so i know the limit for a tune is 90 hp on a 5 speed tranny but... is this on the lb7 with 300hp or the 04.5-05 lly with 310hp?

 

[countryboy95]

also i know some of you will say you've run higher tunes without a prob but just to be on the safe side.

 

[ahduramax]

i would say the 300hp truck. that way your on the low side

 

[ghostrider01]

imo i dont think the allison is gunna even notice 10 hp

 

[barefooter14]

you will be fine with the 90hp tune. i ran it for almost a year till i turned it up to the 3 tune on my ppe and that is running great just take it easy going into 5th gear. if your smart about it you wont have a problem.
