Hey guys, i just replaced my standard rb20 injectors with gtr ones, had to take 35% off the overall fuel trim on the wolf 3d so it wouldnt blow clouds of black smoke, the af ratio on the apexi turbo timer reads 13-1 with a 4000rpm jab of the gas, dont no how acurate it is but. Would you just drive it nice and easy to the dyno or pay the $150 to put it on a tow truck, thanks.

If it starts and runs, and seems to drive o/k, then driving it will not do any damage AT SMALL THROTTLE OPENINGS.

If it is dangerously out of tune, you will know because of the stalling, hesitations, missing, or jerkiness, and it will let you know something is desperately wrong. But even then it will not damage the motor unless you really thrash it.

It is like running out of petrol. The car coughs a bit and stops. You don't melt pistons, break rings, or burn valves just because you run out of petrol.

Take it real easy, and it will be fine.

i would drive it

BUT - keep it off boost. I had to do the same sort of thing when i changed my afm's and injectors, amongst other things. Added enough fuel so it idled and ran, but i kept way off boost. God knows what would have happened with an untuned pfc, larger injectors and some boost

thanks guys, as this was replied to again i thought id let you no that it drove fine. when the turbo started to spool it was blowing a bit of black smoke so i took a fraction more fuel out and just drove it nice and easy.

      I don't think the shuffle can damage the turbos. It only happens at low shaft speeds and loads. It's just annoying (to some people - others are tickled by the effect) and it quite possibly reduces spool performance a little bit.

      Oh dear. The panel beating needs to be done before the filler work. Do you have a photo of the dent before you started? Hard enough to not flex and only hit the high spots?  What do you mean it was just temporary?

      I appreciate the detailed explanation, think I understand now. I spent the better part of last night reading what I could about shuffle and potential solutions. I had replaced the OEM twin turbo pipe with an alternate Y pipe that is separated further away from the turbo. The current one is from HKS and I had a previous pipe that was separated even further away, both have shuffle. I had heard that a divider can be welded in to the OEM pipe to remove turbulence, and figure that aftermarket pipes that are more separated would achieve the same thing. From what I read, most people with -10 turbos get shuffle due to their size, though it's a bit less common with -5s on a standard RB26. I think Nismoid mentioned somewhere it's because OEM recirculation piping is common in Australia with -5 cars. It seems that the recommendation tends to vary between a few options, which I've ordered in what I think is most feasible for me:  1. Retune the MAP or boost controller to try to eliminate shuffle 2. Install OEM recirculation piping 3. Something called a 'balance pipe' welded onto the exhaust manifolds. I don't know if kits for this are available, seems like pure fabrication work 4. simply go single turbo My current layout is as follows: Garrett 2860 -5s HKS Racing Suction intake MAF delete pipes HKS racing chamber intake piping hard intercooler piping,  ARC intercooler HKS SSQV BOV and pipe Haltech 2500 elite ECU and boost solenoid/controller HPI dump pipes OEM exhaust manifolds HKS VCAM step 1 and supporting head modifications Built 2.6 bottom end All OEM recirculation piping was removed, relevant areas sealed off I'll keep an eye out for any alternative solutions but can get started with this.  Only other question is, does shuffle harm the turbo (or anything else)? It seems like some people say your turbo shafts will explode because of the opposing forces after a while and others say they just live with it and adjust their pedal foot accordingly.
