The MadPowerstroke 4088 turbo reveiw
Well we slapped Mad's modified 4088 on my truck at Hunter's today. All I can say is, HOLY SH*T! This turbo is unbelievably smooth and pulls like somebody shoved a freight train under the hood. No surging at all. My EGT's have dropped by a minimum 250-300* at WOT and this thing builds boost instantly. The truck feels several thousand pounds lighter. Overall the turbo runs perfectly and I don't think anyone could ask for more with a completely drop-in turbo.
The best part is that NOTHING was changed in my tuning. No dead spots, no lag, spools as quickly if not a bit quicker than stock and completely cleans up the smoke even with the Atlas 80 FICM tune and a modified version of the Super Panty Dropper from Chris at TSD.
When you apply throttle, the boost comes on extremely fast and smooth. At WOT the truck holds 30psi (stock boost gauge) whereas the stock turbo would fall off to around 24 psi. I know the stock boost sensor only reads up to 30 psi so I believe I'm making more than 30psi.
So far I'm extremely impressed with this turbo. The truck feels much lighter, it runs and responds much smoother. The acceleration is amazing. I'll be taking my truck to Bill at PHP for some dyno pulls soon and I'll keep everyone updated on how this beast continues to perform.
