hey, with the truck in my sign, very very hard to start 4lo, and will choke mid track( need more power or tighter turbo?) , 3rd low will runn all the track loose at 42-300rpm, in 2 nd hi will start at 3500 and go down to 3000 in small class( 7500 lbs and 8500lbs) in 9500lbs or 10500lbs trun will run the same but rpm go down faster, will choke sometimes at the end of the track. have try to play with timing, no real change at higher rpm, just harder to start of the track with higher timing(22*) will a 62 or 64 turbo with the 68mm turbine wheel should be beter? .80 housing or .70? or it just need another turbo(compound)? tanks!
