Gt-500 surging after pulley/tune????

[WHITEMACH]

HI GUYS,
i got a gt500 and put a 2.6 pulley,idler,and a sct tune and a k/n cold air.now when i go out and hammer on it it seems to surge????? what gives ,,,belt slip???? or bad tune??? please help!!!!:shrug:

 

[R1Lello]

describe the surge please

 

[WHITEMACH]

it just feels like it goes then slows, then goes!

That's definitely not "normal" for a Stage II upgrade. I've got the FRPP CAI, VMP Tuning 2.65" pulley and 90mm idler and SCT X3 with tune by Justin at VMP and the driveability is impossible to discern from stock. Well, at least until you nail it, but that's a different thread.

Anyway, there have been NO surging, idling or other issues. Speak to the tuner you bought the package from would be my advice.

Good Luck,
DocGT :beer:

No air leaks? Unmetered air sneaking around the mass air sensor could be a problem.

Was that tune specifically for the K&N? Most guys on here are using JLT, C&L or FRPP cais.

How about he direction of the Mass Air Sensor? It can be put in upside down/backwards.

How about the TCS being active? Do you have factory tires or DR's?
Are your tires spinning at all?

Give JON LUND a call and have him send you a tune.

[Willie2]

[blackshelby]

Did you close the gap up on the spark plugs?

 

[WHITEMACH]

no i did not close the plug gap,,,ill try this ,,,i gotta call tomorrow and find out about the tune! i am running stock tires ,,,,and they suck!!who is john lund???? what is the proper plug gap????

 

[KG/Eleanor]

K/n

Get rid of the K/N cold air intake and get a JLT and the problem should go away.
